A Smarden self-build appeal has been dismissed despite Ashford Borough Council being unable to demonstrate a five-year supply of housing land. Inspector Guy Davies refused permission for two proposed self-build houses on pastureland off Burnthouse Lane on 8th October 2026, giving substantial weight to poor accessibility and harm to rural character.
I would not read the Smarden self-build appeal as a new ban on homes outside villages. The decision applies the August 2026 National Planning Policy Framework (NPPF), including Policy S5 for development outside settlements. The site was approximately a kilometre from Smarden’s settlement boundary, while basic village services were around 1 to 1.6 kilometres away. With unlit lanes lacking separate footways and a limited bus service, the Inspector considered that most journeys would be by car.
The case is relevant to land promoters because Ashford’s accepted housing land supply was only 3.16 years, while ecological improvements and the potential contribution from self-build homes also favoured the proposal. None overcame the conclusion that the site was not physically well related to a settlement. It was a dismissal of a two-home application, not a new statutory rule that automatically prohibits housing beyond 800 metres.
Smarden self-build appeal: decision and application
The Planning Inspectorate appeal record concerns land opposite The Yard, Burnthouse Lane, Smarden, TN27 8PT. The application, PA/2025/1332, proposed two self-build dwellings with garages, cycle and bin storage, access works and landscaping. The appellants were Scarlet, Ben, Hannah and Adam Knight. The appeal proceeded under section 78 of the Town and Country Planning Act 1990 following Ashford’s refusal.
Inspector Guy Davies visited on 29th September and issued the dismissal on 8th October. His full Planning Inspectorate decision letter, identifies two main issues: access to facilities by sustainable transport and the effect on countryside character. The document does not identify a separate costs application or costs award. No other officer is named as a representative deciding this case.
The Inspector described draft Ashford Local Plan 2042 as an early-stage plan carrying little weight. However, the council had already stopped that plan-making process before the appeal decision, following the introduction of a new national plan-making system. It published notice on 30th June 2026 and is now preparing Local Plan 2043. The distinction matters when comparing the wording of an appeal decision with the council’s actual plan-making position.
Why the 800-metre walking test mattered
The appeal site was outside Smarden’s settlement boundary, roughly one kilometre from its edge. The adopted Ashford Local Plan 2030’s Policy HOU5 supports some rural housing where the location is close to a defined settlement and reasonably accessible to everyday facilities or sustainable transport. Its supporting text referred to facilities within 800 metres as an indication of easy walking distance.
For me, the Smarden self-build appeal also shows why the walking route matters as much as a distance measured on a map. The revised National Planning Policy Framework defines reasonable walking distance in Annex B. It refers to around 800 metres or roughly a ten-minute walk where the quality, availability or gradient of routes affects the distance people can reasonably walk. That policy definition is contextual, rather than a universal prohibition on housing beyond a fixed circular radius.
Here the Inspector was concerned with the actual route, not simply the map measurement. Village facilities were between about one and 1.6 kilometres from the site. Walkers and cyclists would share narrow roads with vehicles, with no separate footway or lighting for much of the journey and restricted visibility in places. Bus stops were within walking distance, but the service was very limited.
The recorded accident history was low, which could have supported the applicants’ case on highway safety. Yet an absence of recorded accidents did not establish a convenient, attractive or realistic walking route. The distinction between highway safety and accessibility was important: the Inspector accepted no severe congestion problem but still expected most daily travel to rely on the private car.
New national policies: housing need is not a free pass
Ashford accepted a housing land supply of 3.16 years against the five-year requirement. Policy HO7 of the new Framework gave substantial weight to housing that would meet evidenced needs. The Inspector treated the additional two homes as beneficial, while recognising that the scheme’s small scale limited its actual contribution to closing the district-wide shortfall.
Policy S5(1)(j), however, applies to housing proposed outside settlements when an authority lacks a five-year housing land supply. It still requires development to be physically well related to an existing settlement and appropriately scaled. The Inspector found that the site was too detached from Smarden, particularly when distances and the character of the connecting roads were taken into account.
The Smarden self-build appeal therefore failed to qualify under the housing-shortfall route in Policy S5(1)(j). That is not an absolute bar to every proposal outside the listed categories: Policy S5(4) allows approval in exceptional circumstances where benefits would substantially outweigh adverse effects, including countryside and sustainable travel impacts. The Inspector did not undertake a separate detailed S5(4) analysis, but concluded in the overall planning balance that the housing and ecological benefits did not outweigh the substantial identified harms. A housing shortfall remains a material benefit, not a substitute for a credible site-location case.
Planning Geek has recently covered a separate Lower Broadheath permission-in-principle appeal in which the Inspector also considered the revised settlement policies against housing need. That was a different planning route and a different site; the useful connection is the need to demonstrate the relationship between rural land and the existing settlement, rather than relying only on a shortage of housing.
Open pasture, ponds and a local wildlife site
The land lay within a pasture field in the Haffenden Quarter Farmlands landscape area. Hedges and trees marked parts of its boundary, with a pond in one corner and another pond and small woodland copse in another. There was no national or local landscape designation over the countryside, but the Inspector found that its field pattern and undeveloped nature had intrinsic value.
The houses would occupy a central position along the Burnthouse Lane boundary, creating new domestic plots rather than following the existing hedged field boundaries. Traditional building form and locally sympathetic materials were not sufficient to remove the visual effect of introducing substantial houses into the open field.
The site also fell within the Ponds and Pasture around Smarden Local Wildlife Site AS34. Kent Wildlife Trust raised habitat concerns. The appellants offered a conservation management plan extending to other land they owned, and the Inspector accepted that such management could improve biodiversity and be secured through a condition.
Those possible gains were not dismissed. The Inspector gave modest positive weight to the suggested ecological management and biodiversity benefits, but judged them insufficient to outweigh the substantial harm to access and rural character. It is a useful reminder that habitat improvements do not automatically establish an acceptable location for housing.
Self-build status and the limits of a planning condition
The appellants said the proposed properties were intended as self-build homes. The Inspector acknowledged that self-build and custom-build housing are supported tenures under national policy, but noted that no assessment had been supplied to quantify unmet demand for that type of housing locally.
Nor had a planning obligation been submitted to secure the proposed tenure. The Inspector indicated that a condition would not generally be the right mechanism for that purpose. He nevertheless gave the intended tenure modest beneficial weight. The position highlights the evidential and legal importance of making self-build claims credible rather than merely putting the description into an application form.
The Inspector stated that the scheme would not be required to provide mandatory biodiversity net gain (BNG) as self-build development. The application reference dates from 2025, so it fell within the pre-6th August 2026 regime, under which a qualifying self-build exemption could still apply. The current government BNG exemptions guidance confirms that this dedicated exemption has been removed for new applications made on or after 6th August 2026. The Inspector separately gave modest weight to the volunteered habitat improvements. Because no obligation securing the self-build tenure had been submitted, applicants should also verify the evidence and enforceable mechanism supporting any claimed exemption rather than assuming a self-build label is sufficient.
Why permission opposite the site did not change the result
The appellants pointed to housing under construction opposite Burnthouse Lane, on land formerly known as The Yard. The Inspector recognised similar accessibility difficulties there but distinguished its history. The earlier scheme was redevelopment of previously developed land that provided visual and ecological improvements.
The appeal site was undeveloped pasture, and the proposed houses would not deliver a comparable visual benefit. Other nearby approvals were also mentioned without sufficient detail about the decisions or their planning circumstances. They carried little weight as comparisons. The fact that two parcels face one another across a road does not necessarily put them in the same planning position. The Inspector also gave no decisive weight to the appellants’ suggestion that two existing houses would be released, or to local supporters’ views: the appeal had to be determined on the planning merits rather than the appellants’ personal circumstances.
Ashford’s plan-making timetable has changed
There is a further point worth checking before citing this Smarden self-build appeal in another application. Ashford Borough Council confirms on its current Local Plan pages that work on Local Plan 2042 was stopped following the March 2026 plan-making regulations. The council began a new Local Plan 2043 programme and published a commencement notice on 30th June 2026. Its September scoping consultation closed on 23rd September, before the appeal was determined.
The Inspector’s brief reference to the early-stage Local Plan 2042 therefore should not be taken to mean it was still the active emerging plan when he decided the appeal. The adopted Local Plan 2030 was used for the substantive assessment, alongside the revised national Framework. Anyone working with local policy needs to check which plan-making stage actually applies on the date of their own application or appeal.
What land promoters should take from the decision
The Smarden self-build appeal illustrates a practical three-part test for small rural housing proposals. First, identify the applicable national and adopted local spatial policies. Secondly, demonstrate the actual walking and cycling experience to everyday facilities, not just the straight-line distance or the existence of a road. Thirdly, show how the layout and boundaries preserve landscape character while delivering credible, secured benefits.
For a shortfall-led argument, it remains important to quantify housing supply, but the evidence also has to explain how the proposal fits within the national route for development outside settlements. Where self-build demand, local wildlife management or a previously developed land comparator is advanced, those claims need their own evidence and, where required, enforceable mechanisms.
On 8th October the Inspector found the Smarden scheme wanting on location and landscape despite a substantial district-wide supply deficit. That is the decision’s practical significance. It is not a blanket ruling against self-build or a substitute for examining the merits and policy context of any other site.
