Tunwold, Chadlington — How Independent Design Review, an Appeal Inspector and a Local Authority's Own Senior Conservation and Design Officer Independently Reached the Same Conclusion
Introduction
In April 2025, a Planning Inspector dismissed the Tunwold appeal — not because the original architecture was deficient, but because amendments introduced after submission had eroded the very quality the scheme depended upon.
Those amendments had been introduced at the request of West Oxfordshire District Council's own Senior Conservation and Design Officer.
Ten months later, on the resubmission, the same officer wrote on the public planning record that the original design — the form the Panel had endorsed three times — was the better scheme. The planning committee granted permission unanimously.
This is one of the rarest sequences in the modern Paragraph 84(e) record. The Panel's professional judgement is not corroborated once. It is corroborated twice — by a Planning Inspector and, in writing, by the local authority's own Senior Conservation and Design Officer.
That convergence is rare. It is the strongest evidential outcome a design review process can deliver.
What Paragraph 84(e) Requires
Paragraph 84(e) of the National Planning Policy Framework provides a narrow exception to the general presumption against isolated homes in the countryside. To succeed, a proposal must satisfy a two-limb test:
The design must be truly outstanding and reflect the highest standards in architecture, helping to raise standards more generally in rural areas.
It must significantly enhance its immediate setting and be sensitive to the defining characteristics of the local area.
The threshold is intentionally rigorous. A Paragraph 84(e) submission must demonstrate exceptional architectural and landscape quality through evidence — not assertion.
In a designated landscape such as the Cotswolds National Landscape, the qualitative bar is reinforced by the statutory duty under section 85 of the Countryside and Rights of Way Act 2000, as amended by the Levelling-up and Regeneration Act 2023, to seek to further the purposes of the designation.
Paragraph 84(e) does not yield to opinion. It yields to evidence.
The Site
The application relates to land north of Green End, Chadlington — arable fields and an overgrown former rubble stone quarry on the slopes of the Evenlode Valley, with long views across the surrounding Cotswolds National Landscape. The site sits outside settlement boundaries in development plan terms. The proposal therefore depends entirely upon meeting the Paragraph 84(e) exception.
The former quarry is the architectural starting point. Its faceted, angular geometry — the residue of historical extraction — is read by the design team not as a constraint to disguise but as a defining characteristic of the place to which any new building should respond.
The Proposal
The design, by Hawkes Architecture, is conceived as two distinct architectural acts in dialogue with one another.
The lower volume is faceted, partially buried, and clad in Cotswold stone. Its plan geometry inherits the angular profile of the former quarry walls into which it nestles. The cottage-scaled elements — bedrooms, ancillary spaces, store rooms — are carved into the disturbed ground, their green roofs returning the land surface to vegetation.
Above sits a refined, simple, linear pavilion. Where the lower volume is rooted and faceted, the pavilion is light, ordered and precise. Its single-form geometry establishes a deliberate contrast with the faceted, earthbound base on which it rests. The architectural idea is that contrast: the pavilion's restrained order reading against the quarry-faceted lower level, the two volumes operating as complementary opposites.
The landscape strategy, developed by Davies Landscape Architecture, addresses ecological enhancement, visual integration and the framing of long views across the surrounding countryside. Reflecting ponds are set into the former quarry floor. Wildflower meadow restoration, hedgerow reinstatement and the recovery of disturbed ground form a structural landscape proposition that reads as part of the architectural argument, not separately from it.
This is a coherent, authored architectural proposition — two volumes, one idea, one disciplined relationship to its setting. That single-mindedness is central to what follows.
Independent Design Review: Three Iterations
The scheme is reviewed by the Panel on three occasions across the design development period. The Panel is a national, multidisciplinary, independent design review service operating in accordance with the principles set out in Design Review: Principles and Practice and reflecting the expectation in paragraph 138 of the National Planning Policy Framework that local planning authorities have regard to the outcome of design review processes when assessing applications.
Paragraph 84(e) is not a design competition; it is a policy test. Proposals very rarely succeed in a single iteration. Exceptional quality is most reliably reached through structured, iterative scrutiny — a process by which siting, scale, mass, materiality, sustainability and landscape strategy are tested and refined. The Panel's role is to interrogate, not to validate.
By the third session, the Panel records that the proposal meets the Paragraph 84(e) threshold. The architectural language is clear and disciplined. The contrast between the faceted lower volume and the simple linear pavilion above is coherent. The composition reads as a single, considered response to the former quarry within its setting.
That conclusion is recorded in the Panel's written feedback and is subsequently relied upon in the officer report.
The Panel notes for transparency that West Oxfordshire District Council's Senior Conservation and Design Officer is invited to attend each of the three design review sessions. On each occasion, the invitation is declined. This sequence — and the relevance of that sequence to what follows — is set out further in the next section.
"Obtaining full endorsement from an independent design panel for a Paragraph 84(e) scheme is an important milestone. It proves that the scheme has undergone rigorous examination by a multidisciplinary group of design experts — architects, landscape architects, ecologists, sustainability specialists, planning, urban design, arboriculture and any other specific skills depending on the context of the project. At Tunwold, achieving that support was a process covering three separate design reviews." - Richard Hawkes, Hawkes Architecture
Officer Recommendation: Material Weight to the Panel's Findings
The officer report to West Oxfordshire District Council's Uplands Planning Sub-Committee acknowledges that the site is within the Cotswolds National Landscape and contrary to development plan location policy, and that the proposal can only be justified under Paragraph 84(e).
The report attributes material weight to the Panel's iterative engagement and final endorsement, and to paragraph 138 of the National Planning Policy Framework, which identifies design review as a tool to which local planning authorities should have regard.
On that basis, officers conclude that the Paragraph 84(e) criteria are met and propose approval, subject to conditions.
This is a significant governance point. At officer level, the Panel's feedback is correctly treated as a material consideration, transparently recorded in the report, and used to support a recommendation for approval.
Planning Committee: Refusal, Against Officer Recommendation
On 11 December 2023 — eight months after the application was submitted — the Uplands Planning Sub-Committee refuses the application, contrary to the officer recommendation.
Architectural quality is, by its nature, a matter of trained judgement. Members reach a different conclusion to officers and to the Panel on whether the Paragraph 84(e) criteria are met. The reasons for refusal are recorded in the formal decision notice.
Committees are entitled to depart from officer recommendations. The planning system is a democratic system, and this is part of how it functions.
The interest of this case lies not in the refusal itself, but in what subsequently happens between submission and appeal.
A Single Internal Voice — and a Material Change
Between the submission of the application and the consideration of the case, an amendment is introduced at the request of West Oxfordshire District Council's Senior Conservation and Design Officer. The Senior Conservation and Design Officer's view, expressed in the consultation response, is that the simple, straight first-floor pavilion form needs altering "to break down the simple strident form" and proposes that the upper storey be "cranked" in plan above the faceted ground-floor volume below.
This amendment does not originate with the design team. It does not originate with the Panel. It does not emerge from a public consultation response from any other consultee. It is introduced after the application is registered, in response to a single internal officer comment.
The Panel's third-iteration endorsement relates to the original simple, straight pavilion form — the form whose architectural logic is the contrast it draws against the faceted lower volume. The cranked version is not the form the Panel reviewed.
The same Senior Conservation and Design Officer who introduces the amendment is the officer who, on each of the three previous occasions, declined the invitation to attend the design review sessions at which the Panel tested and ultimately endorsed the simple, straight pavilion form.
This is the pivot point of the case.
The Planning Appeal: Dismissal on Design Grounds
The appeal (APP/D3125/W/24/3344303) is heard on 4 March 2025 — fifteen months after the committee refusal. The Inspector dismisses the appeal in April 2025. But the architectural reasoning sits at the centre of the decision.
The Inspector concludes that the cranking of the upper storey, introduced after submission, has eroded the refined elegance of the pavilion building and weakened the contrast it makes with the faceted ground floor building upon which it nestles. The Inspector's view is that the amendments have over-articulated the geometry of the pavilion and weakened its connection with the landscape.
The architectural argument the Inspector identifies is precisely the architectural argument the Panel had identified in its third review: a refined, restrained linear pavilion reading against a faceted, earthbound base. The Inspector finds that argument intact in the originally submitted form. The Inspector finds it eroded in the form before the appeal.
This is the line on which the entire case turns:
The proposition that fails at appeal is not the proposition the Panel reviewed.
A single internal amendment, introduced after submission by an officer who had declined to attend the iterative review process, has changed the building. The Inspector's finding identifies the change. The Panel's finding had identified the original.
Resubmission: A Return to the Panel-Endorsed Form
In July 2025, the applicant resubmits a revised application. The cranking of the upper storey is removed. The simple, straight pavilion form returns. The architectural proposition reviewed by the Panel is reinstated. Ecology surveys are re-commissioned because the original surveys are now out of date.
What happens next is the part of the story that almost never appears in the modern planning record.
In the consultation response on the resubmission, the same Senior Conservation and Design Officer who had requested the cranking concedes the point — in writing, on the public record:
"I note that the inspector at the appeal took exception to our suggested cranking of the plan of the upper storey — and, with hindsight, I agree that the cranked plan is not as successful as the simple straight block."
That single sentence ends the matter.
It is a candid, professional acknowledgement that the original Panel-endorsed form is the better scheme. It is on the public planning record. It has been written by an officer of the same authority that requested the amendment in the first place.
The officer report to committee on the resubmission supports approval, making clear the views of the Inspector. On 16 February 2026, the planning committee unanimously votes to support that recommendation. Permission is finally granted.
Paragraph 138 of the NPPF and the Role of Design Review
Paragraph 138 of the National Planning Policy Framework states that local planning authorities should, when appropriate, seek the views of statutory and non-statutory consultees, including independent design review panels, and have regard to their assessments where relevant.
The Tunwold sequence illustrates the practical purpose of that policy provision. Independent design review is most effective when it is engaged early, applied iteratively, and respected through to determination. Where it is overridden after the fact by parties who did not participate in the iterative review process, the evidential chain is disrupted — and, as Tunwold demonstrates, the consequences travel directly into the appeal record.
The case is a worked example of why design review feedback is most useful when it is treated, as paragraph 138 indicates, as a material consideration to be carried through the determination process intact — and of why those who introduce material design amendments after that process should ideally have participated in it.
Paragraph 139 and Significant Weight
Paragraph 139 of the National Planning Policy Framework provides that significant weight should be given to outstanding or innovative designs that promote high levels of sustainability or help to raise the standard of design more generally in an area, where these fit within the grain of their surroundings.
Both the original application and the resubmission rely upon the principle in paragraph 139. The unanimous approval of the resubmission reflects a consensus, by officers and elected members, that this principle is engaged on the simple, straight, Panel-endorsed form.
What Tunwold Demonstrates
Tunwold sits alongside Spilsby House (East Devon, 2025) as one of the strongest publicly evidenced cases for the role of independent design review in Paragraph 84(e) decision-making in England. The two cases reach the same essential conclusion through different routes.
Spilsby House: officer recommendation for approval, committee refusal, appeal allowed — the Inspector independently reaching the same conclusion as the Panel.
Tunwold: officer recommendation for approval, committee refusal, appeal dismissed on the basis that a post-submission amendment has weakened the design — the simple, Panel-endorsed form subsequently reinstated and approved unanimously, with the local authority's own Senior Conservation and Design Officer confirming in writing that the original was the better scheme.
In both cases, the Panel's professional judgement is independently corroborated. In Tunwold, that corroboration arrives not from one source but from two — a Planning Inspector and the local authority's own Senior Conservation and Design Officer.
What This Means for You
Conclusion
Tunwold is not a story of disagreement. It is a story of three independent professional bodies — the Panel, the Planning Inspectorate, and the local authority's own Senior Conservation and Design Officer — independently reaching the same conclusion about the architectural quality of the original scheme.
That convergence is rare. It is the strongest evidential outcome a design review process can deliver — not that the Panel is right because it says so, but that the same professional judgement is reached independently by a Planning Inspector and confirmed candidly, in writing, by the local authority's own design officer.
Paragraph 84(e) does not yield to opinion. It yields to evidence. Tunwold is the evidence.
About the Panel
Frequently Asked Questions
What is Paragraph 84(e) of the National Planning Policy Framework?
Paragraph 84(e) is a narrow exception in national planning policy that allows an isolated home in the countryside where the design is of exceptional quality, reflecting the highest standards in architecture, helping to raise standards more generally in rural areas, and significantly enhancing its immediate setting. The threshold is intentionally high.
What weight does the National Planning Policy Framework give to independent design review?
Paragraph 138 of the National Planning Policy Framework states that local planning authorities should, when appropriate, seek the views of statutory and non-statutory consultees, including independent design review panels, and have regard to their assessments where relevant.
Why was the Tunwold appeal dismissed?
The Inspector concluded that amendments to the upper-storey pavilion, introduced after submission at the request of the local authority's Senior Conservation and Design Officer, had eroded the refined elegance of the pavilion and weakened the contrast it made with the faceted ground floor building upon which it nestles. The Inspector found that the amendments had over-articulated the geometry of the pavilion and weakened its connection with the landscape.
What changed between the original application and the resubmission?
The cranking of the upper storey was removed. The simple, straight pavilion form — the form originally endorsed by the Panel across three iterations — was reinstated. Permission was granted unanimously on 16 February 2026.
Can a planning committee refuse a Paragraph 84(e) scheme that officers support?
Yes. Planning committees are entitled to depart from officer recommendations. Where they do, the architectural and policy reasoning is tested independently by a Planning Inspector if the applicant appeals.
How does The Design Review Panel engage with applicants?
The Panel engages with applicants from the earliest stages of design development, applies structured multidisciplinary scrutiny across multiple iterations, and produces an evidential record that can be relied upon by local planning authorities, Planning Inspectors and elected members. Engagement is most effective when it is early, iterative and respected through to determination.
Is The Design Review Panel independent of local planning authorities?
Yes. The Panel is a national, independent, multidisciplinary design review service. Its feedback reflects the professional judgement of its members and is not directed by, or accountable to, any local planning authority.
