1. Introduction
This formal objection is submitted in response to planning application S26/0451/FUL, which seeks full planning permission for the erection of 30 dwellings on land south of Cirencester Road, Minchinhampton. The application is made by Cotswold Homes Ltd and is supported by a Planning Statement prepared by Planning Ventures Ltd (Rev B, March 2026, ref. PV.1517).
This objection is made on substantive planning grounds, engaging the National Planning Policy Framework (NPPF, December 2024), the Stroud District Local Plan (adopted November 2015) and the Minchinhampton Neighbourhood Development Plan 2018–2036 (NDP, made July 2019). It is further supported by the objections raised by Minchinhampton Parish Council. It is respectfully submitted that the application must be refused for the reasons set out below.
2. Applicable Policy Framework
The application falls to be determined under Section 38(6) of the Planning and Compulsory Purchase Act 2004, in accordance with the development plan unless material considerations indicate otherwise. The relevant development plan comprises:
• Stroud District Local Plan (November 2015): Core Policies CP2, CP3, CP14 and CP15; Delivery Policies HC1, HC4, ES3, ES6, ES7 and ES10;
• Minchinhampton Neighbourhood Development Plan 2018–2036 (made July 2019): Policies MP Env 1, MP Env 3, MP Env 4, MP Dev 1, MP Traffic 1, MP Traffic 2, MP Transport 1, MP Transport 2, MP Parking 2 and MP PRoW 1; and
• National Planning Policy Framework (December 2024): in particular Paragraphs 11, 15, 115, 187, 189 and 190.
The site lies outside the defined settlement development limit of Minchinhampton, within the Cotswolds National Landscape (AONB), and within the core catchment zone of Rodborough Common Special Area of Conservation (SAC) and the Zone of Influence of the Cotswold Beechwoods SAC. These designations are decisive in the determination of this application.
3. NPPF: Statutory Duty to Protect the Cotswolds National Landscape
3.1 Section 85 CROW Act 2000, as strengthened by the Levelling-up and Regeneration Act 2023
The site lies within an open, unbuilt agricultural field forming part of the Cotswolds National Landscape. Under Section 85 of the Countryside and Rights of Way Act 2000, as strengthened by Section 245 of the Levelling-up and Regeneration Act 2023, Stroud District Council (SDC) is subject to a duty to seek to further the purpose of conserving and enhancing the natural beauty of the National Landscape in exercising any function affecting land within or adjacent to it. This is a more demanding obligation than the previous 'duty of regard' and requires a pro-active, demonstrable approach; it is not a discretionary policy test.
3.2 NPPF Paragraph 189
NPPF Paragraph 189 requires that great weight be given to conserving and enhancing landscape and scenic beauty in National Landscapes, which have the highest status of protection. The scale and extent of development within all designated areas should be limited. A 30-dwelling residential estate — together with a sewage pumping station, a 150-metre sewer trench crossing Cirencester Road, lighting, engineered estate roads, construction compounds and a minimum two-year construction period — on an open, elevated AONB plateau is not limited in scale or extent. This site has been refused development on precisely these grounds, including at appeal in 2014 on the very same land.
3.3 Major Development in a National Landscape: NPPF Paragraph 190
The applicant contends that the proposals do not constitute 'major development' in the National Landscape, arguing by reference to the percentage of Minchinhampton's existing housing stock (approximately 1.18%) that the scheme is proportionately small. This is not the correct legal test. NPPF Footnote 67 to Paragraph 190 confirms that whether a proposal is 'major development' is a matter for the decision maker, taking into account its nature, scale and setting, and whether it could have a significant adverse impact on the purposes for which the area has been designated or defined. Quantity relative to existing stock is irrelevant to this assessment.
It is noted that Planning Ventures Ltd's Planning Statement (PV.1517) cites 'NPPF Footnote 87' for this test. There is no Footnote 87 in the December 2024 NPPF. The correct reference is Footnote 67. This is a material error that undermines the credibility of the agent's policy analysis throughout.
Thirty dwellings, a pumping station, engineered drainage, a 150-metre trench crossing a road resurfaced in March 2026, estate roads, lighting and a minimum two-year construction period on an open AONB slope constitute major development on any proper contextual assessment. This conclusion is reinforced by three directly comparable local Inspector and Committee decisions: the 2014 appeal dismissal on this very site (APP/C1625/A/14/2212196), the 2022 dismissal at The Knapp for 35 dwellings (APP/C1625/W/22/3300819), and the 2025 refusal of two small sheds on the immediately adjacent field (S.24/1121/FUL).
Where major development is proposed within a National Landscape, NPPF Paragraph 190 requires the applicant to demonstrate both exceptional circumstances and that the development is in the national interest. No such case is advanced. The application fails this test entirely, and must be refused on this ground alone.
4. Stroud District Local Plan 2015: Policy Conflicts
4.1 Core Policy CP2 – Strategic Growth and Development Locations
Core Policy CP2 establishes that outside the six identified strategic growth sites, all development will take place in accordance with the settlement hierarchy set out in CP3. Housing development will take place within settlement development limits. The application site lies outside the defined settlement development limit of Minchinhampton and is not one of the six strategic sites. It fails CP2.
The applicant argues that CP2 is out of date because SDC cannot demonstrate a five-year housing land supply (currently 3.24 years) and that the NPPF Paragraph 11(d) tilted balance therefore applies. This argument fails. The applicant's own Planning Statement acknowledges that National Landscapes fall within Footnote 7 to NPPF Paragraph 11(d)(i) as policies that protect areas of particular importance providing a clear reason for refusing development. The presumption in favour of sustainable development is therefore disapplied. The housing land supply shortfall carries no weight in this determination.
4.2 Core Policy CP3 – Settlement Hierarchy
Core Policy CP3 requires proposals for new development to be located in accordance with the District's settlement hierarchy to ensure development reduces the need to travel and promotes sustainable communities. Minchinhampton is correctly identified as a Second Tier Local Service Centre. The policy requires housing development to take place within the defined settlement development limits of such centres. The application site is outside those limits, is not allocated in the Local Plan or the NDP, and does not comply with CP3.
4.3 Core Policy CP14 – High Quality Sustainable Development
Core Policy CP14 requires that development will only be supported where it achieves all fourteen listed criteria. The proposal demonstrably fails three of these on the evidence submitted. Criterion 2 requires no unacceptable levels of noise, water or other pollution: no noise assessment has been provided for the cumulative cattle grid impacts, and no hydraulic assessment has been provided for the downstream sewer network. Criterion 3 requires adequate foul drainage and sewage capacity to serve the development: the only capacity confirmation has expired and is assessed against the wrong number of dwellings. Criterion 13 requires safe and convenient access on foot, by cycle and by connection to existing footways: the access design is unsafe in real-world conditions as set out in Section 8 below. The application fails CP14 on each of these criteria independently.
4.4 Core Policy CP15 – A Quality Living and Working Countryside
Core Policy CP15 states that proposals outside identified settlement development limits will not be permitted except where they fall within one of six specific exceptions: (1) essential maintenance or enhancement of a sustainable farming or forestry enterprise; (2) essential for public enjoyment of the countryside or rural economy through employment, sport, leisure or tourism; (3) a rural exception site that is appropriate, sustainable, affordable and meets an identified local need; (4) enabling development required to maintain a heritage asset of acknowledged importance; (5) a replacement dwelling; or (6) essential community facilities.
This proposal falls within none of these six exceptions. It is speculative open-market residential development on an agricultural field. The applicant's argument that CP15 is out of date by virtue of the housing land supply position fails for the same reason as the CP2 argument: the tilted balance is disapplied by NPPF Paragraph 11(d)(i) and the National Landscape designation. CP15 remains a full material policy resisting this development.
The Parish Council has noted the development does not constitute an affordable housing exception scheme under Delivery Policy HC4. This is correct: HC4 permits planning permission for affordable housing on sites adjoining settlement development limits where clearly evidenced local need exists and the site is accessible to a range of local services. This proposal is overwhelmingly open-market housing (19 of 30 units), not a rural exception affordable housing scheme. HC4 provides no route to permission here.
4.5 Delivery Policy HC1 – Meeting Small-Scale Housing Need Within Defined Settlements
Delivery Policy HC1 grants permission for residential development within defined settlement development limits where, amongst other criteria, the housing is of a scale, density, layout and design compatible with the character of the settlement, and edge-of-settlement proposals would not appear as an intrusion into the countryside and would retain a sense of transition between open countryside and the settlement's core. The application site lies outside the defined settlement development limit entirely. HC1 by its terms applies to development within limits. The proposal does not comply with HC1, and in any event a 30-dwelling estate on an open AONB field plainly constitutes an intrusion into the countryside contrary to HC1's third criterion.
4.6 Delivery Policy ES3 – Maintaining Quality of Life Within Environmental Limits
Delivery Policy ES3 provides that permission will not be granted to any development which would be likely to lead to or result in an unacceptable level of, amongst others: criterion 1 — noise, general disturbance, smell, fumes, loss of daylight or sunlight, loss of privacy or an overbearing effect; and criterion 5 — a detrimental impact on highway safety.
On criterion 1: the proposal introduces a new cattle grid at the site entrance on Cirencester Road. There are already two existing cattle grids within approximately 100 metres (one at the existing surgery access). The NDP's own evidence base, including the Helix Transport Appraisal commissioned for the NDP (NDP section 6.10), expressly records the conflicts between cattle and traffic on Cirencester Road and the frequency of accidents. Noise levels of 80–90 dB occur when vehicles traverse existing grids. No noise assessment has been submitted addressing the cumulative impact of three cattle grids on residential amenity. The application fails ES3 criterion 1.
On criterion 5: the access design is materially unsafe in real-world conditions for the reasons set out in Section 8 below. The application fails ES3 criterion 5.
4.7 Delivery Policy ES6 – Providing for Biodiversity and Geodiversity (European Sites)
Delivery Policy ES6 requires that development must not result in significant adverse effects on SACs, either alone or in combination with other plans and projects. With specific regard to recreational impacts, the Local Plan establishes a 3 km core catchment zone around Rodborough Common SAC (paragraph 6.41). The application site lies within both this zone and the wider 3.9 km Zone of Influence identified by the applicant's own Ecological Impact Assessment (EcIA paragraph 4.1.9).
The applicant has followed the mechanism in Local Plan paragraph 6.41, proposing financial contributions of £994 per dwelling towards the Rodborough Common SAC Avoidance and Mitigation Strategy and £673 per dwelling (£193 SAMM + £480 SANG) towards the Cotswold Beechwoods SAC Mitigation Strategy, both to be secured by Section 106 agreement. These figures are drawn from the 2022 Footprint Ecology mitigation strategies.
This approach is in principle the correct one. However, three deficiencies mean it cannot be approved as submitted. First, the per-dwelling rates were calculated in 2022 against anticipated housing growth over the Local Plan period. The December 2025 Shard Lake spill and the 2024–25 CSO failure data at Avening STW represent a material change in the ecological condition of the catchment since those rates were set. Natural England has not confirmed that the 2022 rates remain adequate in light of these developments. Second, the Section 106 heads of terms are described as draft only. Until the contributions are formally agreed and executed, SAC mitigation is undeliverable and cannot lawfully be relied upon. Third, there is a direct discrepancy between the EcIA (which states the Rodborough Common SAC Zone of Influence as 3.9 km at paragraph 4.1.9) and the Local Plan (which defines the core catchment zone as 3 km). The S106 mechanism in paragraph 6.41 is tied to the Local Plan's 3 km definition: the wider 3.9 km zone may require a bespoke appropriate assessment rather than reliance on the pooled mitigation strategy alone. Natural England's view on this discrepancy has not been sought. Until the contributions are confirmed as adequate by Natural England, formally agreed in an executed S106, and the zone-of-influence discrepancy resolved, the application cannot be approved consistently with ES6 or the Conservation of Habitats and Species Regulations 2017.
4.8 Delivery Policy ES7 – Landscape Character
Delivery Policy ES7 gives priority to the conservation and enhancement of the natural and scenic beauty of the Cotswolds AONB and states that major development will not be permitted unless it is demonstrated to be in the national interest and that there is a lack of alternative sustainable development sites. This mirrors the NPPF Paragraph 190 test and fails for the same reasons. In addition, development will only be permitted if it meets both of ES7's two criteria: (1) the location, materials, scale and use are sympathetic and complement the landscape character; and (2) natural features including trees, hedgerows and water features that contribute to landscape character are retained and managed appropriately. The proposal suburbanises an open AONB field that the NDP itself (Map 4, NDP section 3.16) identifies as potentially species-rich grassland on the south of Cirencester Road. It does not complement the Wold Tops landscape character. It fails both ES7 criteria and the major development test.
5. Minchinhampton Neighbourhood Development Plan 2018–2036
The NDP was made in July 2019 and forms part of the statutory development plan carrying full legal weight. The correct policy codes are those in the NDP itself. There are no policies numbered 'MP1', 'MP2', 'MP3' or 'MP4' in the NDP — these shorthand references in some consultation material do not correspond to the document's actual policy codes. The relevant policies and their correct identifiers are as follows.
5.1 Policy MP Env 1 – Landscape Conservation
Policy MP Env 1 states that the Parish Council will seek to ensure decisions on new development have regard to SDC Policy ES7 Landscape Character, including the use of appropriate materials, whilst recognising that within the parish some limited development within the AONB may be necessary. It also supports Local Plan Policy ES8 for the enhancement and expansion of tree and woodland resources.
Two points arise. First, while the NDP acknowledges that some limited AONB development may be necessary, it ties this to ES7 compliance — which this proposal fails for the reasons in section 4.8 above. The concession is conditional and cannot be used to justify 30 dwellings on an open AONB field. Second, the NDP's own supporting text (paragraph 3.5) expressly states that any development around Minchinhampton would be within the AONB and that the major development test therefore applies to any proposal. The NDP does not qualify or dilute this test.
5.2 Policy MP Env 3 – Nature Conservation
Policy MP Env 3 requires proposals to protect and practically conserve statutorily designated sites, Key Wildlife Sites and other priority habitats including grasslands of high biodiversity value and watercourses. It requires developments to demonstrate that the conservation status of protected species will be maintained. The NDP's own Map 4 (section 3.16–3.17) identifies areas of potential species-rich grassland on the south of Cirencester Road immediately east of the town, which corresponds to the application site. No species-rich grassland survey has been submitted. The Ecological Impact Assessment acknowledges the loss of 74% of on-site habitat units and relies entirely on off-site offsetting. This approach is inconsistent with the mandatory Biodiversity Gain Hierarchy, as confirmed by SDC's own BNG Officer in a holding objection submitted to this application. SDC's BNG Officer has found that the removal of virtually all Medium distinctiveness calcareous grassland and its proposed off-site offsetting directly breaches Articles 37A and 37D of the Town and Country Planning (Development Management Procedure) (England) Order 2015, which require on-site avoidance and mitigation before off-site compensation can be used. The application fails MP Env 3 and the mandatory BNG statutory framework.
5.3 Policy MP Env 4 – Minchinhampton Common
Policy MP Env 4 states that development proposals will only be supported if they comply with the NPPF, the Stroud Local Plan and the other policies of the NDP. It further supports traffic management measures to reduce speed across the Common and protect run-back grazing land within the parish. The NDP (paragraph 3.31) records that around 450 cattle graze the Common every summer and that the success of grazing depends on the continued existence of grassland sites as 'run-back land.' The application site is adjacent to and visually connected to the Common. Increasing traffic on Cirencester Road through additional dwellings, and adding a third cattle grid to an already constrained section of road, is contrary to the objectives of MP Env 4 and to the long-term viability of Common grazing on which the SSSI depends.
5.4 Policy MP Dev 1 – New Development
Policy MP Dev 1 supports development proposals that demonstrate, amongst other things: a high standard of design that respects and reinforces local distinctiveness through matters of scale, density, massing and height; respect for the natural environment and terrain; and respect for the setting of listed buildings and heritage assets. The development fails to demonstrate these criteria. It urbanises an open AONB plateau field on the eastern edge of the village without establishing that its scale and impact are appropriate. The applicant's landscape assessment itself accepts Moderate Adverse to Minor Adverse visual effects diminishing only over 15 years.
5.5 Policy MP Traffic 1 – Transport Statement Requirement
Policy MP Traffic 1 requires that planning applications for developments with any impact on local road networks be accompanied by a Transport Statement that clearly identifies the travel, transport and road safety issues associated with the proposed development, and that takes into account the particular challenges that affect the Parish and demonstrates how it will contribute to enhancing and improving the local transportation environment including parking and road safety.
The submitted Transport Statement fails this test. The NDP's own evidence base (Chapter 6 and Appendix 2, the Helix Transport Appraisal) sets out in detail the particular challenges that affect the Parish: cattle on Cirencester Road and the frequency of vehicle-cattle conflicts, the poor sightlines and narrowness of roads, the queuing caused by the calming bollard east of the proposed access, the inadequacy of footways, and the constrained crossing at the top of Butt Street. The Transport Statement addresses none of these matters. It does not take into account the cattle grids, the bollard-induced queuing, or the peak-hour stacking that makes the claimed 120-metre visibility splay fictitious in real-world conditions. The application fails Policy MP Traffic 1.
5.6 Policies MP Traffic 2, MP Transport 1 and 2, MP Parking 2 and MP PRoW 1
Policy MP Traffic 2 requires development proposals to contribute to the improvement of traffic movement and circulation within the Parish, especially around the centres of communities and schools. Policy MP Transport 1 requires proposals to be well located to reduce reliance on private cars. Policy MP Transport 2 requires safe and convenient walking and cycling routes to local services. Policy MP Parking 2 requires evidence that the level of off-street parking will ensure no detrimental impact on the local road network. Policy MP PRoW 1 requires new development to protect and where possible enhance the existing rights of way network and its ambience. The proposal makes no contribution to any of these objectives and adds traffic pressure and highway conflict to an already constrained section of road. It fails all of these policies.
6. Foul Drainage: No Deliverable or Lawful Solution
6.1 Expired and Defective Severn Trent Evidence
The applicant's foul drainage strategy relies on a Severn Trent Developer Enquiry letter dated 24 July 2025, which expired on 24 January 2026. The application was validated on 27 March 2026 — more than two months after expiry. There is therefore no valid capacity confirmation from the statutory undertaker at the date of validation or determination. In addition, the letter assessed 29 dwellings (not 30), and predates the December 2025 Shard Lake spill and the 2024–25 CSO failure data. The drainage evidence base is invalid.
6.2 Unapproved Pumped Connection
Severn Trent identified two gravity connection options: MH6140 and MH16001. Neither requires a pumping station. The applicant instead proposes a pumped connection into MH6140 — an option that Severn Trent has not approved. The gravity route to MH16001 avoids a pumping station, rising main, emergency storage and the need to trench Cirencester Road. The only barrier to this gravity option is Common Land consent, which the applicant has not sought. The proposed drainage solution is therefore both unapproved and avoidable.
6.3 Existing Sewer Failures
Avening Sewage Treatment Works recorded over 154 spills totalling 975 hours in 2024 alone. A further spill reached the Shard Lake system in December 2025. The RO Small House CSO has also recorded failures. No hydraulic modelling, CCTV survey or infiltration testing of the receiving network has been undertaken since 2021. The network is demonstrably failing under existing loading; additional loading from 30 dwellings is unacceptable under CP14 criterion 3 and ES3 criterion 2.
6.4 Ancient Infrastructure and Unknown Network Condition
The foul network serving this part of Minchinhampton is understood to include sections of asbestos-cement pipework and salt-glazed clay pipes of 1920s to 1950s construction. No records of surveys, installation dates or renewal works exist for the Cirencester Road system or the original Tynings estate sewer. A pressurised pumped connection to such infrastructure carries an unacceptably high risk of surge failure, joint displacement, backflow and catastrophic overflow during power loss. These risks have not been assessed.
6.5 Section 58 Resurfacing Prohibition
Cirencester Road was resurfaced in March 2026 following statutory notices in February 2026. Section 58 of the New Roads and Street Works Act 1991 may prohibit excavation for up to five years following resurfacing. The proposed 150-metre trench crosses this highway. The application was submitted on 27 March 2026 with full knowledge of these works and no evidence of exemption. A mandatory physical Grampian condition preventing development until the drainage connection is made would stall the scheme indefinitely. The deliverability failure was foreseeable and has not been addressed.
7. Statutory Biodiversity Net Gain: Mandatory Legislative Failure
Biodiversity net gain (BNG) is a mandatory requirement for all major development applications determined on or after 12 February 2024, under Schedule 7A to the Town and Country Planning Act 1990 (inserted by the Environment Act 2021). This application was validated on 27 March 2026 and is therefore subject to the mandatory 10% BNG requirement. SDC's own BNG Officer has reviewed the submitted Biodiversity Metric, Ecological Impact Assessment, Baseline Habitat Plan and Post-Development Habitat Plan and has issued a holding objection identifying three statutory failures. Unless all three are resolved, SDC cannot lawfully approve a Biodiversity Gain Plan for this application.
7.1 Omission of Individual Trees from the Biodiversity Metric
The BNG Officer has identified, from review of recent aerial photography, the presence of several small trees along the northern and western boundaries of the application site. These trees do not appear in the Biodiversity Metric calculations or on either of the submitted habitat plans. If these trees have any distinctiveness rating — even Low — their omission understates the baseline unit total, increases the gap to the mandatory 10% net gain, and renders the current metric calculations unreliable. If they are of Medium or above distinctiveness, they also engage the Biodiversity Gain Hierarchy issue identified in section 7.2 below. The BNG Officer has requested clarification and, if the trees have been omitted in error, updated Metric calculations and habitat plans.
7.2 Breach of the Mandatory Biodiversity Gain Hierarchy
This is the most legally significant of the three failures. The Biodiversity Gain Hierarchy is set out in Articles 37A and 37D of the Town and Country Planning (Development Management Procedure) (England) Order 2015 (as amended). It establishes a strict priority order that must be followed for Medium or above distinctiveness on-site habitats adversely affected by development. The developer must first demonstrate that adverse effects cannot be avoided; then mitigate those effects on site (through enhancement of existing habitats and creation of new on-site habitats) before off-site gain allocation is used; and off-site allocation must be exhausted before statutory biodiversity credits are purchased.
The BNG Officer has found that the application, as submitted, removes virtually all of the site's Medium distinctiveness calcareous grassland — 1.462 ha of Other Calcareous Grassland recorded in the Metric as Other Neutral Grassland — and proposes to compensate this loss primarily through off-site habitat units. This is a direct breach of the mandatory Hierarchy. The Hierarchy requires the applicant to demonstrate first that the loss of that calcareous grassland cannot be avoided, and then that on-site mitigation has been maximised before any resort to off-site offsetting.
This is not a minor procedural deficiency. Proper compliance with the Hierarchy would require the scheme to retain more of the calcareous grassland on site, which in turn requires reducing the developable footprint of the application. The BNG Officer's holding objection is therefore potentially fatal to the scheme as currently designed: any revision that genuinely satisfies the Hierarchy is likely to result in materially fewer dwellings. The application cannot be approved in its current form.
7.3 Ecological Infeasibility of Proposed On-Site Habitat Creation
The BNG Officer has raised significant concerns about the ecological feasibility of the proposed on-site habitat creation. The majority of replacement habitat creation is concentrated in the south-eastern corner of the site, where a combination of other calcareous grassland, wet grassland, individual trees, hedgerows, mixed scrub and SuDS features are proposed. The BNG Officer has found that these habitat types have conflicting ecological requirements in terms of soil type, nutrient levels, hydrology, shading and long-term management, and that delivering this combination within such a limited area is not ecologically credible.
In addition, the narrow strips of calcareous grassland proposed along the northern part of the site are considered too small and poorly connected to be ecologically viable or sustainable in the long term. These concerns are material: the Biodiversity Metric calculations rely on the delivery of these habitats achieving the projected condition scores over time. If delivery is infeasible, the metric projections are unreliable and the claimed 10% net gain cannot be verified.
7.4 Significance: SDC Cannot Lawfully Approve a Non-Compliant Biodiversity Gain Plan
The BNG Officer's holding objection is not a public representation — it is an internal specialist objection from SDC's own officer. A planning committee cannot lawfully resolve to grant permission where the mandatory Biodiversity Gain Plan condition cannot be satisfied in compliance with the Hierarchy. The BNG requirement under the Environment Act 2021 and Schedule 7A of the TCPA 1990 is a statutory obligation that runs alongside the planning system and is not subject to planning judgment or override by other material considerations. Until all three deficiencies identified by the BNG Officer are resolved to the officer's satisfaction, this application cannot proceed to determination.
8. Highways: Unsafe Access and Understated Impact
8.1 Visibility Splays Unachievable in Real-World Conditions
The applicant claims that visibility to the east of up to 120 metres is achievable. This does not reflect real-world conditions on Cirencester Road. Traffic eastbound is routinely queued and stationary because the traffic-calming bollard approximately 30 metres east of the proposed access restricts the east-to-west lane. During peak periods — which the NDP's Helix Transport Appraisal records commence from 06:00 — a driver emerging from the proposed estate road junction would face stationary or slow-moving vehicles, not a clear sightline. The visibility assessment is based on idealised empty-road conditions. NPPF Paragraph 115 requires refusal on highway grounds where there would be an unacceptable impact on highway safety. The cumulative scenario here meets that test.
8.2 Unsafe Access Design
The proposed access is positioned opposite the surgery entrance and immediately adjacent to a deteriorating existing cattle grid. The centre section of that grid has dropped. The interaction between the proposed estate road junction, the surgery access, the calming bollard, the existing cattle grids and livestock movements has not been assessed in the Transport Statement. NDP Policy MP Traffic 1 requires the Transport Statement to take into account the particular challenges that affect the Parish. It does not do so. The access design may be theoretically compliant on paper but is materially unsafe in practice, contrary to NPPF Paragraph 115 and Local Plan Delivery Policy ES3 criterion 5.
8.3 Cumulative Highways Impact
The Transport Statement claims that 30 dwellings will generate only sixteen two-way trips in the morning peak, with 'no significant impact.' This assessment ignores the cumulative constraints documented in the NDP's own transport chapter: surgery traffic, school bus routes, livestock movements crossing Cirencester Road, three cattle grids, the calming bollard and commuter flows to Stroud, Tetbury, Cirencester and Cheltenham. No cumulative impact assessment has been undertaken as required by NDP Policy MP Traffic 1. The conclusions of the Transport Statement are untenable.
9. Material Precedents Requiring Refusal
The following decisions are directly material to this application and each independently supports refusal:
• 2014 Appeal on this precise site (APP/C1625/A/14/2212196): a single dwelling was refused on 16 December 2013 and the appeal dismissed on 8 May 2014 for unacceptable harm to the character and appearance of the AONB and failure to conserve its natural beauty. Thirty dwellings cause exponentially greater harm.
• The Knapp, 2022 (S.20/2667/FUL; APP/C1625/W/22/3300819): 35 dwellings refused on 20 May 2022 and appeal dismissed on 24 October 2022 for unacceptable effects on the AONB and failure to demonstrate exceptional circumstances for major development. The Inspector confirmed the preferred direction for growth was to the east — meaning Tobacconist Road — not this site.
• Playschool for Dogs, 2025 (S.24/1121/FUL): two small sheds refused on 4 September 2025 for 'minor landscape clutter' on the field immediately adjacent to the application site. If two sheds are unacceptable on the adjacent field, 30 dwellings are plainly unacceptable here.
• Eastington, February 2026 (S.25/2138/FUL): SDC refused 34 dwellings on 24 February 2026 relying on the 2015 Local Plan policies CP2, CP3, CP14, CP15, ES6, ES7, ES10 and ES12. The same policy framework applies here, with the additional and more severe constraints of the AONB, the Rodborough Common SAC Zone of Influence and the expired drainage evidence.
The applicant's reliance on an abandoned draft Local Plan allocation at Tobacconist Road is misconceived. The Tobacconist Road allocation (PS05) was never examined, was reduced from 100 to 80 dwellings before withdrawal, was heavily objected to, and was abandoned when the 2021 emerging plan was rejected by Inspectors. It carries no weight. It is also on the opposite side of Minchinhampton from this site and does not assist the applicant's case in any respect.
10. The Tilted Balance is Disapplied
The applicant asserts that the tilted balance under NPPF Paragraph 11(d) applies in favour of the development because SDC cannot demonstrate a five-year housing land supply. This argument is legally incorrect. The applicant's own Planning Statement confirms that National Landscapes fall within Footnote 7 to NPPF Paragraph 11(d), which identifies the NPPF policies protecting areas of particular importance that engage Paragraph 11(d)(i). That sub-paragraph provides that permission should not be granted where such policies provide a clear reason for refusing the development proposed. Both the Cotswolds National Landscape designation and the Rodborough Common SAC Zone of Influence provide such a clear reason. The housing land supply shortfall carries no weight in this determination. The applicant's own evidence base defeats their planning balance argument.
11. Light Pollution and Tranquillity
The application site forms part of the east–west landscape corridor connecting the open plateau between The Knapp to the west and Hyde to the east. This corridor is characterised by dark skies, tranquillity and the absence of suburban development. The NDP (section 3.3) records that the site is within the 'High Wold' landscape character zone and notes the importance of open grassland and the connectivity of the plateau. The submitted Landscape and Visual Appraisal accepts Moderate Adverse visual effects for adjacent receptors diminishing over 15 years. These effects are unacceptable in an AONB context. Permanent lighting of an estate road, domestic gardens and parking courts on a currently dark plateau field would harm the tranquillity and dark sky character of this part of the National Landscape.
12. Parish Council Objections
The Parish Council's objections are adopted and endorsed in full. In summary, the Parish Council has correctly identified the following grounds, each of which is substantiated above:
• NPPF Paragraph 189 requires the scale and extent of development within AONBs to be limited; this proposal fails that requirement;
• The development does not fall within any of the six exception categories in Local Plan Policy CP15;
• The development does not constitute a strategic growth location under Policy CP2;
• The site falls outside the settlement development limit and does not figure in the settlement hierarchy for housing development under Policy CP3;
• The development is not small-scale provision within the settlement limit meeting local housing need as required by Policy HC1;
• Rodborough Common SAC mitigation contributions rely on 2022 per-dwelling rates that have not been confirmed as still adequate by Natural England, and are not yet secured in an executed Section 106 agreement; and
• The development does not constitute an affordable housing rural exception scheme under Policy HC4.
Should, contrary to all of the above, the Council be minded to grant permission, the Parish Council has requested the following, which are fully supported:
• A substantial contribution to town centre development (in accordance with NDP sections 4.34–4.36 and 7.10);
• Improvement of the pedestrian crossing on Cirencester Road at the top of Butt Street (NDP Phase 1 project, section 7.21, identified as Medium cost priority);
• Large-scale investment in infrastructure — sewage, water supply, telecommunications and electrical supply — to meet both the needs of the development and future development (NDP sections 4.57–4.65, which make clear that development must help solve existing problems rather than exacerbate them); and
• Adoption of internal highways by Gloucestershire County Council under a Section 38 Agreement.
This formal objection is submitted in response to planning application S26/0451/FUL, which seeks full planning permission for the erection of 30 dwellings on land south of Cirencester Road, Minchinhampton. The application is made by Cotswold Homes Ltd and is supported by a Planning Statement prepared by Planning Ventures Ltd (Rev B, March 2026, ref. PV.1517).
This objection is made on substantive planning grounds, engaging the National Planning Policy Framework (NPPF, December 2024), the Stroud District Local Plan (adopted November 2015) and the Minchinhampton Neighbourhood Development Plan 2018–2036 (NDP, made July 2019). It is further supported by the objections raised by Minchinhampton Parish Council. It is respectfully submitted that the application must be refused for the reasons set out below.
2. Applicable Policy Framework
The application falls to be determined under Section 38(6) of the Planning and Compulsory Purchase Act 2004, in accordance with the development plan unless material considerations indicate otherwise. The relevant development plan comprises:
• Stroud District Local Plan (November 2015): Core Policies CP2, CP3, CP14 and CP15; Delivery Policies HC1, HC4, ES3, ES6, ES7 and ES10;
• Minchinhampton Neighbourhood Development Plan 2018–2036 (made July 2019): Policies MP Env 1, MP Env 3, MP Env 4, MP Dev 1, MP Traffic 1, MP Traffic 2, MP Transport 1, MP Transport 2, MP Parking 2 and MP PRoW 1; and
• National Planning Policy Framework (December 2024): in particular Paragraphs 11, 15, 115, 187, 189 and 190.
The site lies outside the defined settlement development limit of Minchinhampton, within the Cotswolds National Landscape (AONB), and within the core catchment zone of Rodborough Common Special Area of Conservation (SAC) and the Zone of Influence of the Cotswold Beechwoods SAC. These designations are decisive in the determination of this application.
3. NPPF: Statutory Duty to Protect the Cotswolds National Landscape
3.1 Section 85 CROW Act 2000, as strengthened by the Levelling-up and Regeneration Act 2023
The site lies within an open, unbuilt agricultural field forming part of the Cotswolds National Landscape. Under Section 85 of the Countryside and Rights of Way Act 2000, as strengthened by Section 245 of the Levelling-up and Regeneration Act 2023, Stroud District Council (SDC) is subject to a duty to seek to further the purpose of conserving and enhancing the natural beauty of the National Landscape in exercising any function affecting land within or adjacent to it. This is a more demanding obligation than the previous 'duty of regard' and requires a pro-active, demonstrable approach; it is not a discretionary policy test.
3.2 NPPF Paragraph 189
NPPF Paragraph 189 requires that great weight be given to conserving and enhancing landscape and scenic beauty in National Landscapes, which have the highest status of protection. The scale and extent of development within all designated areas should be limited. A 30-dwelling residential estate — together with a sewage pumping station, a 150-metre sewer trench crossing Cirencester Road, lighting, engineered estate roads, construction compounds and a minimum two-year construction period — on an open, elevated AONB plateau is not limited in scale or extent. This site has been refused development on precisely these grounds, including at appeal in 2014 on the very same land.
3.3 Major Development in a National Landscape: NPPF Paragraph 190
The applicant contends that the proposals do not constitute 'major development' in the National Landscape, arguing by reference to the percentage of Minchinhampton's existing housing stock (approximately 1.18%) that the scheme is proportionately small. This is not the correct legal test. NPPF Footnote 67 to Paragraph 190 confirms that whether a proposal is 'major development' is a matter for the decision maker, taking into account its nature, scale and setting, and whether it could have a significant adverse impact on the purposes for which the area has been designated or defined. Quantity relative to existing stock is irrelevant to this assessment.
It is noted that Planning Ventures Ltd's Planning Statement (PV.1517) cites 'NPPF Footnote 87' for this test. There is no Footnote 87 in the December 2024 NPPF. The correct reference is Footnote 67. This is a material error that undermines the credibility of the agent's policy analysis throughout.
Thirty dwellings, a pumping station, engineered drainage, a 150-metre trench crossing a road resurfaced in March 2026, estate roads, lighting and a minimum two-year construction period on an open AONB slope constitute major development on any proper contextual assessment. This conclusion is reinforced by three directly comparable local Inspector and Committee decisions: the 2014 appeal dismissal on this very site (APP/C1625/A/14/2212196), the 2022 dismissal at The Knapp for 35 dwellings (APP/C1625/W/22/3300819), and the 2025 refusal of two small sheds on the immediately adjacent field (S.24/1121/FUL).
Where major development is proposed within a National Landscape, NPPF Paragraph 190 requires the applicant to demonstrate both exceptional circumstances and that the development is in the national interest. No such case is advanced. The application fails this test entirely, and must be refused on this ground alone.
4. Stroud District Local Plan 2015: Policy Conflicts
4.1 Core Policy CP2 – Strategic Growth and Development Locations
Core Policy CP2 establishes that outside the six identified strategic growth sites, all development will take place in accordance with the settlement hierarchy set out in CP3. Housing development will take place within settlement development limits. The application site lies outside the defined settlement development limit of Minchinhampton and is not one of the six strategic sites. It fails CP2.
The applicant argues that CP2 is out of date because SDC cannot demonstrate a five-year housing land supply (currently 3.24 years) and that the NPPF Paragraph 11(d) tilted balance therefore applies. This argument fails. The applicant's own Planning Statement acknowledges that National Landscapes fall within Footnote 7 to NPPF Paragraph 11(d)(i) as policies that protect areas of particular importance providing a clear reason for refusing development. The presumption in favour of sustainable development is therefore disapplied. The housing land supply shortfall carries no weight in this determination.
4.2 Core Policy CP3 – Settlement Hierarchy
Core Policy CP3 requires proposals for new development to be located in accordance with the District's settlement hierarchy to ensure development reduces the need to travel and promotes sustainable communities. Minchinhampton is correctly identified as a Second Tier Local Service Centre. The policy requires housing development to take place within the defined settlement development limits of such centres. The application site is outside those limits, is not allocated in the Local Plan or the NDP, and does not comply with CP3.
4.3 Core Policy CP14 – High Quality Sustainable Development
Core Policy CP14 requires that development will only be supported where it achieves all fourteen listed criteria. The proposal demonstrably fails three of these on the evidence submitted. Criterion 2 requires no unacceptable levels of noise, water or other pollution: no noise assessment has been provided for the cumulative cattle grid impacts, and no hydraulic assessment has been provided for the downstream sewer network. Criterion 3 requires adequate foul drainage and sewage capacity to serve the development: the only capacity confirmation has expired and is assessed against the wrong number of dwellings. Criterion 13 requires safe and convenient access on foot, by cycle and by connection to existing footways: the access design is unsafe in real-world conditions as set out in Section 8 below. The application fails CP14 on each of these criteria independently.
4.4 Core Policy CP15 – A Quality Living and Working Countryside
Core Policy CP15 states that proposals outside identified settlement development limits will not be permitted except where they fall within one of six specific exceptions: (1) essential maintenance or enhancement of a sustainable farming or forestry enterprise; (2) essential for public enjoyment of the countryside or rural economy through employment, sport, leisure or tourism; (3) a rural exception site that is appropriate, sustainable, affordable and meets an identified local need; (4) enabling development required to maintain a heritage asset of acknowledged importance; (5) a replacement dwelling; or (6) essential community facilities.
This proposal falls within none of these six exceptions. It is speculative open-market residential development on an agricultural field. The applicant's argument that CP15 is out of date by virtue of the housing land supply position fails for the same reason as the CP2 argument: the tilted balance is disapplied by NPPF Paragraph 11(d)(i) and the National Landscape designation. CP15 remains a full material policy resisting this development.
The Parish Council has noted the development does not constitute an affordable housing exception scheme under Delivery Policy HC4. This is correct: HC4 permits planning permission for affordable housing on sites adjoining settlement development limits where clearly evidenced local need exists and the site is accessible to a range of local services. This proposal is overwhelmingly open-market housing (19 of 30 units), not a rural exception affordable housing scheme. HC4 provides no route to permission here.
4.5 Delivery Policy HC1 – Meeting Small-Scale Housing Need Within Defined Settlements
Delivery Policy HC1 grants permission for residential development within defined settlement development limits where, amongst other criteria, the housing is of a scale, density, layout and design compatible with the character of the settlement, and edge-of-settlement proposals would not appear as an intrusion into the countryside and would retain a sense of transition between open countryside and the settlement's core. The application site lies outside the defined settlement development limit entirely. HC1 by its terms applies to development within limits. The proposal does not comply with HC1, and in any event a 30-dwelling estate on an open AONB field plainly constitutes an intrusion into the countryside contrary to HC1's third criterion.
4.6 Delivery Policy ES3 – Maintaining Quality of Life Within Environmental Limits
Delivery Policy ES3 provides that permission will not be granted to any development which would be likely to lead to or result in an unacceptable level of, amongst others: criterion 1 — noise, general disturbance, smell, fumes, loss of daylight or sunlight, loss of privacy or an overbearing effect; and criterion 5 — a detrimental impact on highway safety.
On criterion 1: the proposal introduces a new cattle grid at the site entrance on Cirencester Road. There are already two existing cattle grids within approximately 100 metres (one at the existing surgery access). The NDP's own evidence base, including the Helix Transport Appraisal commissioned for the NDP (NDP section 6.10), expressly records the conflicts between cattle and traffic on Cirencester Road and the frequency of accidents. Noise levels of 80–90 dB occur when vehicles traverse existing grids. No noise assessment has been submitted addressing the cumulative impact of three cattle grids on residential amenity. The application fails ES3 criterion 1.
On criterion 5: the access design is materially unsafe in real-world conditions for the reasons set out in Section 8 below. The application fails ES3 criterion 5.
4.7 Delivery Policy ES6 – Providing for Biodiversity and Geodiversity (European Sites)
Delivery Policy ES6 requires that development must not result in significant adverse effects on SACs, either alone or in combination with other plans and projects. With specific regard to recreational impacts, the Local Plan establishes a 3 km core catchment zone around Rodborough Common SAC (paragraph 6.41). The application site lies within both this zone and the wider 3.9 km Zone of Influence identified by the applicant's own Ecological Impact Assessment (EcIA paragraph 4.1.9).
The applicant has followed the mechanism in Local Plan paragraph 6.41, proposing financial contributions of £994 per dwelling towards the Rodborough Common SAC Avoidance and Mitigation Strategy and £673 per dwelling (£193 SAMM + £480 SANG) towards the Cotswold Beechwoods SAC Mitigation Strategy, both to be secured by Section 106 agreement. These figures are drawn from the 2022 Footprint Ecology mitigation strategies.
This approach is in principle the correct one. However, three deficiencies mean it cannot be approved as submitted. First, the per-dwelling rates were calculated in 2022 against anticipated housing growth over the Local Plan period. The December 2025 Shard Lake spill and the 2024–25 CSO failure data at Avening STW represent a material change in the ecological condition of the catchment since those rates were set. Natural England has not confirmed that the 2022 rates remain adequate in light of these developments. Second, the Section 106 heads of terms are described as draft only. Until the contributions are formally agreed and executed, SAC mitigation is undeliverable and cannot lawfully be relied upon. Third, there is a direct discrepancy between the EcIA (which states the Rodborough Common SAC Zone of Influence as 3.9 km at paragraph 4.1.9) and the Local Plan (which defines the core catchment zone as 3 km). The S106 mechanism in paragraph 6.41 is tied to the Local Plan's 3 km definition: the wider 3.9 km zone may require a bespoke appropriate assessment rather than reliance on the pooled mitigation strategy alone. Natural England's view on this discrepancy has not been sought. Until the contributions are confirmed as adequate by Natural England, formally agreed in an executed S106, and the zone-of-influence discrepancy resolved, the application cannot be approved consistently with ES6 or the Conservation of Habitats and Species Regulations 2017.
4.8 Delivery Policy ES7 – Landscape Character
Delivery Policy ES7 gives priority to the conservation and enhancement of the natural and scenic beauty of the Cotswolds AONB and states that major development will not be permitted unless it is demonstrated to be in the national interest and that there is a lack of alternative sustainable development sites. This mirrors the NPPF Paragraph 190 test and fails for the same reasons. In addition, development will only be permitted if it meets both of ES7's two criteria: (1) the location, materials, scale and use are sympathetic and complement the landscape character; and (2) natural features including trees, hedgerows and water features that contribute to landscape character are retained and managed appropriately. The proposal suburbanises an open AONB field that the NDP itself (Map 4, NDP section 3.16) identifies as potentially species-rich grassland on the south of Cirencester Road. It does not complement the Wold Tops landscape character. It fails both ES7 criteria and the major development test.
5. Minchinhampton Neighbourhood Development Plan 2018–2036
The NDP was made in July 2019 and forms part of the statutory development plan carrying full legal weight. The correct policy codes are those in the NDP itself. There are no policies numbered 'MP1', 'MP2', 'MP3' or 'MP4' in the NDP — these shorthand references in some consultation material do not correspond to the document's actual policy codes. The relevant policies and their correct identifiers are as follows.
5.1 Policy MP Env 1 – Landscape Conservation
Policy MP Env 1 states that the Parish Council will seek to ensure decisions on new development have regard to SDC Policy ES7 Landscape Character, including the use of appropriate materials, whilst recognising that within the parish some limited development within the AONB may be necessary. It also supports Local Plan Policy ES8 for the enhancement and expansion of tree and woodland resources.
Two points arise. First, while the NDP acknowledges that some limited AONB development may be necessary, it ties this to ES7 compliance — which this proposal fails for the reasons in section 4.8 above. The concession is conditional and cannot be used to justify 30 dwellings on an open AONB field. Second, the NDP's own supporting text (paragraph 3.5) expressly states that any development around Minchinhampton would be within the AONB and that the major development test therefore applies to any proposal. The NDP does not qualify or dilute this test.
5.2 Policy MP Env 3 – Nature Conservation
Policy MP Env 3 requires proposals to protect and practically conserve statutorily designated sites, Key Wildlife Sites and other priority habitats including grasslands of high biodiversity value and watercourses. It requires developments to demonstrate that the conservation status of protected species will be maintained. The NDP's own Map 4 (section 3.16–3.17) identifies areas of potential species-rich grassland on the south of Cirencester Road immediately east of the town, which corresponds to the application site. No species-rich grassland survey has been submitted. The Ecological Impact Assessment acknowledges the loss of 74% of on-site habitat units and relies entirely on off-site offsetting. This approach is inconsistent with the mandatory Biodiversity Gain Hierarchy, as confirmed by SDC's own BNG Officer in a holding objection submitted to this application. SDC's BNG Officer has found that the removal of virtually all Medium distinctiveness calcareous grassland and its proposed off-site offsetting directly breaches Articles 37A and 37D of the Town and Country Planning (Development Management Procedure) (England) Order 2015, which require on-site avoidance and mitigation before off-site compensation can be used. The application fails MP Env 3 and the mandatory BNG statutory framework.
5.3 Policy MP Env 4 – Minchinhampton Common
Policy MP Env 4 states that development proposals will only be supported if they comply with the NPPF, the Stroud Local Plan and the other policies of the NDP. It further supports traffic management measures to reduce speed across the Common and protect run-back grazing land within the parish. The NDP (paragraph 3.31) records that around 450 cattle graze the Common every summer and that the success of grazing depends on the continued existence of grassland sites as 'run-back land.' The application site is adjacent to and visually connected to the Common. Increasing traffic on Cirencester Road through additional dwellings, and adding a third cattle grid to an already constrained section of road, is contrary to the objectives of MP Env 4 and to the long-term viability of Common grazing on which the SSSI depends.
5.4 Policy MP Dev 1 – New Development
Policy MP Dev 1 supports development proposals that demonstrate, amongst other things: a high standard of design that respects and reinforces local distinctiveness through matters of scale, density, massing and height; respect for the natural environment and terrain; and respect for the setting of listed buildings and heritage assets. The development fails to demonstrate these criteria. It urbanises an open AONB plateau field on the eastern edge of the village without establishing that its scale and impact are appropriate. The applicant's landscape assessment itself accepts Moderate Adverse to Minor Adverse visual effects diminishing only over 15 years.
5.5 Policy MP Traffic 1 – Transport Statement Requirement
Policy MP Traffic 1 requires that planning applications for developments with any impact on local road networks be accompanied by a Transport Statement that clearly identifies the travel, transport and road safety issues associated with the proposed development, and that takes into account the particular challenges that affect the Parish and demonstrates how it will contribute to enhancing and improving the local transportation environment including parking and road safety.
The submitted Transport Statement fails this test. The NDP's own evidence base (Chapter 6 and Appendix 2, the Helix Transport Appraisal) sets out in detail the particular challenges that affect the Parish: cattle on Cirencester Road and the frequency of vehicle-cattle conflicts, the poor sightlines and narrowness of roads, the queuing caused by the calming bollard east of the proposed access, the inadequacy of footways, and the constrained crossing at the top of Butt Street. The Transport Statement addresses none of these matters. It does not take into account the cattle grids, the bollard-induced queuing, or the peak-hour stacking that makes the claimed 120-metre visibility splay fictitious in real-world conditions. The application fails Policy MP Traffic 1.
5.6 Policies MP Traffic 2, MP Transport 1 and 2, MP Parking 2 and MP PRoW 1
Policy MP Traffic 2 requires development proposals to contribute to the improvement of traffic movement and circulation within the Parish, especially around the centres of communities and schools. Policy MP Transport 1 requires proposals to be well located to reduce reliance on private cars. Policy MP Transport 2 requires safe and convenient walking and cycling routes to local services. Policy MP Parking 2 requires evidence that the level of off-street parking will ensure no detrimental impact on the local road network. Policy MP PRoW 1 requires new development to protect and where possible enhance the existing rights of way network and its ambience. The proposal makes no contribution to any of these objectives and adds traffic pressure and highway conflict to an already constrained section of road. It fails all of these policies.
6. Foul Drainage: No Deliverable or Lawful Solution
6.1 Expired and Defective Severn Trent Evidence
The applicant's foul drainage strategy relies on a Severn Trent Developer Enquiry letter dated 24 July 2025, which expired on 24 January 2026. The application was validated on 27 March 2026 — more than two months after expiry. There is therefore no valid capacity confirmation from the statutory undertaker at the date of validation or determination. In addition, the letter assessed 29 dwellings (not 30), and predates the December 2025 Shard Lake spill and the 2024–25 CSO failure data. The drainage evidence base is invalid.
6.2 Unapproved Pumped Connection
Severn Trent identified two gravity connection options: MH6140 and MH16001. Neither requires a pumping station. The applicant instead proposes a pumped connection into MH6140 — an option that Severn Trent has not approved. The gravity route to MH16001 avoids a pumping station, rising main, emergency storage and the need to trench Cirencester Road. The only barrier to this gravity option is Common Land consent, which the applicant has not sought. The proposed drainage solution is therefore both unapproved and avoidable.
6.3 Existing Sewer Failures
Avening Sewage Treatment Works recorded over 154 spills totalling 975 hours in 2024 alone. A further spill reached the Shard Lake system in December 2025. The RO Small House CSO has also recorded failures. No hydraulic modelling, CCTV survey or infiltration testing of the receiving network has been undertaken since 2021. The network is demonstrably failing under existing loading; additional loading from 30 dwellings is unacceptable under CP14 criterion 3 and ES3 criterion 2.
6.4 Ancient Infrastructure and Unknown Network Condition
The foul network serving this part of Minchinhampton is understood to include sections of asbestos-cement pipework and salt-glazed clay pipes of 1920s to 1950s construction. No records of surveys, installation dates or renewal works exist for the Cirencester Road system or the original Tynings estate sewer. A pressurised pumped connection to such infrastructure carries an unacceptably high risk of surge failure, joint displacement, backflow and catastrophic overflow during power loss. These risks have not been assessed.
6.5 Section 58 Resurfacing Prohibition
Cirencester Road was resurfaced in March 2026 following statutory notices in February 2026. Section 58 of the New Roads and Street Works Act 1991 may prohibit excavation for up to five years following resurfacing. The proposed 150-metre trench crosses this highway. The application was submitted on 27 March 2026 with full knowledge of these works and no evidence of exemption. A mandatory physical Grampian condition preventing development until the drainage connection is made would stall the scheme indefinitely. The deliverability failure was foreseeable and has not been addressed.
7. Statutory Biodiversity Net Gain: Mandatory Legislative Failure
Biodiversity net gain (BNG) is a mandatory requirement for all major development applications determined on or after 12 February 2024, under Schedule 7A to the Town and Country Planning Act 1990 (inserted by the Environment Act 2021). This application was validated on 27 March 2026 and is therefore subject to the mandatory 10% BNG requirement. SDC's own BNG Officer has reviewed the submitted Biodiversity Metric, Ecological Impact Assessment, Baseline Habitat Plan and Post-Development Habitat Plan and has issued a holding objection identifying three statutory failures. Unless all three are resolved, SDC cannot lawfully approve a Biodiversity Gain Plan for this application.
7.1 Omission of Individual Trees from the Biodiversity Metric
The BNG Officer has identified, from review of recent aerial photography, the presence of several small trees along the northern and western boundaries of the application site. These trees do not appear in the Biodiversity Metric calculations or on either of the submitted habitat plans. If these trees have any distinctiveness rating — even Low — their omission understates the baseline unit total, increases the gap to the mandatory 10% net gain, and renders the current metric calculations unreliable. If they are of Medium or above distinctiveness, they also engage the Biodiversity Gain Hierarchy issue identified in section 7.2 below. The BNG Officer has requested clarification and, if the trees have been omitted in error, updated Metric calculations and habitat plans.
7.2 Breach of the Mandatory Biodiversity Gain Hierarchy
This is the most legally significant of the three failures. The Biodiversity Gain Hierarchy is set out in Articles 37A and 37D of the Town and Country Planning (Development Management Procedure) (England) Order 2015 (as amended). It establishes a strict priority order that must be followed for Medium or above distinctiveness on-site habitats adversely affected by development. The developer must first demonstrate that adverse effects cannot be avoided; then mitigate those effects on site (through enhancement of existing habitats and creation of new on-site habitats) before off-site gain allocation is used; and off-site allocation must be exhausted before statutory biodiversity credits are purchased.
The BNG Officer has found that the application, as submitted, removes virtually all of the site's Medium distinctiveness calcareous grassland — 1.462 ha of Other Calcareous Grassland recorded in the Metric as Other Neutral Grassland — and proposes to compensate this loss primarily through off-site habitat units. This is a direct breach of the mandatory Hierarchy. The Hierarchy requires the applicant to demonstrate first that the loss of that calcareous grassland cannot be avoided, and then that on-site mitigation has been maximised before any resort to off-site offsetting.
This is not a minor procedural deficiency. Proper compliance with the Hierarchy would require the scheme to retain more of the calcareous grassland on site, which in turn requires reducing the developable footprint of the application. The BNG Officer's holding objection is therefore potentially fatal to the scheme as currently designed: any revision that genuinely satisfies the Hierarchy is likely to result in materially fewer dwellings. The application cannot be approved in its current form.
7.3 Ecological Infeasibility of Proposed On-Site Habitat Creation
The BNG Officer has raised significant concerns about the ecological feasibility of the proposed on-site habitat creation. The majority of replacement habitat creation is concentrated in the south-eastern corner of the site, where a combination of other calcareous grassland, wet grassland, individual trees, hedgerows, mixed scrub and SuDS features are proposed. The BNG Officer has found that these habitat types have conflicting ecological requirements in terms of soil type, nutrient levels, hydrology, shading and long-term management, and that delivering this combination within such a limited area is not ecologically credible.
In addition, the narrow strips of calcareous grassland proposed along the northern part of the site are considered too small and poorly connected to be ecologically viable or sustainable in the long term. These concerns are material: the Biodiversity Metric calculations rely on the delivery of these habitats achieving the projected condition scores over time. If delivery is infeasible, the metric projections are unreliable and the claimed 10% net gain cannot be verified.
7.4 Significance: SDC Cannot Lawfully Approve a Non-Compliant Biodiversity Gain Plan
The BNG Officer's holding objection is not a public representation — it is an internal specialist objection from SDC's own officer. A planning committee cannot lawfully resolve to grant permission where the mandatory Biodiversity Gain Plan condition cannot be satisfied in compliance with the Hierarchy. The BNG requirement under the Environment Act 2021 and Schedule 7A of the TCPA 1990 is a statutory obligation that runs alongside the planning system and is not subject to planning judgment or override by other material considerations. Until all three deficiencies identified by the BNG Officer are resolved to the officer's satisfaction, this application cannot proceed to determination.
8. Highways: Unsafe Access and Understated Impact
8.1 Visibility Splays Unachievable in Real-World Conditions
The applicant claims that visibility to the east of up to 120 metres is achievable. This does not reflect real-world conditions on Cirencester Road. Traffic eastbound is routinely queued and stationary because the traffic-calming bollard approximately 30 metres east of the proposed access restricts the east-to-west lane. During peak periods — which the NDP's Helix Transport Appraisal records commence from 06:00 — a driver emerging from the proposed estate road junction would face stationary or slow-moving vehicles, not a clear sightline. The visibility assessment is based on idealised empty-road conditions. NPPF Paragraph 115 requires refusal on highway grounds where there would be an unacceptable impact on highway safety. The cumulative scenario here meets that test.
8.2 Unsafe Access Design
The proposed access is positioned opposite the surgery entrance and immediately adjacent to a deteriorating existing cattle grid. The centre section of that grid has dropped. The interaction between the proposed estate road junction, the surgery access, the calming bollard, the existing cattle grids and livestock movements has not been assessed in the Transport Statement. NDP Policy MP Traffic 1 requires the Transport Statement to take into account the particular challenges that affect the Parish. It does not do so. The access design may be theoretically compliant on paper but is materially unsafe in practice, contrary to NPPF Paragraph 115 and Local Plan Delivery Policy ES3 criterion 5.
8.3 Cumulative Highways Impact
The Transport Statement claims that 30 dwellings will generate only sixteen two-way trips in the morning peak, with 'no significant impact.' This assessment ignores the cumulative constraints documented in the NDP's own transport chapter: surgery traffic, school bus routes, livestock movements crossing Cirencester Road, three cattle grids, the calming bollard and commuter flows to Stroud, Tetbury, Cirencester and Cheltenham. No cumulative impact assessment has been undertaken as required by NDP Policy MP Traffic 1. The conclusions of the Transport Statement are untenable.
9. Material Precedents Requiring Refusal
The following decisions are directly material to this application and each independently supports refusal:
• 2014 Appeal on this precise site (APP/C1625/A/14/2212196): a single dwelling was refused on 16 December 2013 and the appeal dismissed on 8 May 2014 for unacceptable harm to the character and appearance of the AONB and failure to conserve its natural beauty. Thirty dwellings cause exponentially greater harm.
• The Knapp, 2022 (S.20/2667/FUL; APP/C1625/W/22/3300819): 35 dwellings refused on 20 May 2022 and appeal dismissed on 24 October 2022 for unacceptable effects on the AONB and failure to demonstrate exceptional circumstances for major development. The Inspector confirmed the preferred direction for growth was to the east — meaning Tobacconist Road — not this site.
• Playschool for Dogs, 2025 (S.24/1121/FUL): two small sheds refused on 4 September 2025 for 'minor landscape clutter' on the field immediately adjacent to the application site. If two sheds are unacceptable on the adjacent field, 30 dwellings are plainly unacceptable here.
• Eastington, February 2026 (S.25/2138/FUL): SDC refused 34 dwellings on 24 February 2026 relying on the 2015 Local Plan policies CP2, CP3, CP14, CP15, ES6, ES7, ES10 and ES12. The same policy framework applies here, with the additional and more severe constraints of the AONB, the Rodborough Common SAC Zone of Influence and the expired drainage evidence.
The applicant's reliance on an abandoned draft Local Plan allocation at Tobacconist Road is misconceived. The Tobacconist Road allocation (PS05) was never examined, was reduced from 100 to 80 dwellings before withdrawal, was heavily objected to, and was abandoned when the 2021 emerging plan was rejected by Inspectors. It carries no weight. It is also on the opposite side of Minchinhampton from this site and does not assist the applicant's case in any respect.
10. The Tilted Balance is Disapplied
The applicant asserts that the tilted balance under NPPF Paragraph 11(d) applies in favour of the development because SDC cannot demonstrate a five-year housing land supply. This argument is legally incorrect. The applicant's own Planning Statement confirms that National Landscapes fall within Footnote 7 to NPPF Paragraph 11(d), which identifies the NPPF policies protecting areas of particular importance that engage Paragraph 11(d)(i). That sub-paragraph provides that permission should not be granted where such policies provide a clear reason for refusing the development proposed. Both the Cotswolds National Landscape designation and the Rodborough Common SAC Zone of Influence provide such a clear reason. The housing land supply shortfall carries no weight in this determination. The applicant's own evidence base defeats their planning balance argument.
11. Light Pollution and Tranquillity
The application site forms part of the east–west landscape corridor connecting the open plateau between The Knapp to the west and Hyde to the east. This corridor is characterised by dark skies, tranquillity and the absence of suburban development. The NDP (section 3.3) records that the site is within the 'High Wold' landscape character zone and notes the importance of open grassland and the connectivity of the plateau. The submitted Landscape and Visual Appraisal accepts Moderate Adverse visual effects for adjacent receptors diminishing over 15 years. These effects are unacceptable in an AONB context. Permanent lighting of an estate road, domestic gardens and parking courts on a currently dark plateau field would harm the tranquillity and dark sky character of this part of the National Landscape.
12. Parish Council Objections
The Parish Council's objections are adopted and endorsed in full. In summary, the Parish Council has correctly identified the following grounds, each of which is substantiated above:
• NPPF Paragraph 189 requires the scale and extent of development within AONBs to be limited; this proposal fails that requirement;
• The development does not fall within any of the six exception categories in Local Plan Policy CP15;
• The development does not constitute a strategic growth location under Policy CP2;
• The site falls outside the settlement development limit and does not figure in the settlement hierarchy for housing development under Policy CP3;
• The development is not small-scale provision within the settlement limit meeting local housing need as required by Policy HC1;
• Rodborough Common SAC mitigation contributions rely on 2022 per-dwelling rates that have not been confirmed as still adequate by Natural England, and are not yet secured in an executed Section 106 agreement; and
• The development does not constitute an affordable housing rural exception scheme under Policy HC4.
Should, contrary to all of the above, the Council be minded to grant permission, the Parish Council has requested the following, which are fully supported:
• A substantial contribution to town centre development (in accordance with NDP sections 4.34–4.36 and 7.10);
• Improvement of the pedestrian crossing on Cirencester Road at the top of Butt Street (NDP Phase 1 project, section 7.21, identified as Medium cost priority);
• Large-scale investment in infrastructure — sewage, water supply, telecommunications and electrical supply — to meet both the needs of the development and future development (NDP sections 4.57–4.65, which make clear that development must help solve existing problems rather than exacerbate them); and
• Adoption of internal highways by Gloucestershire County Council under a Section 38 Agreement.
