Findon PIP appeal: self-build cannot simply be secured

A claimed self-build benefit cannot be assumed to be legally secured at every stage of the planning process. In this Findon PIP appeal, the Inspector acknowledged that a planning obligation could potentially secure self-build at technical details consent, but found there was no mechanism at the permission-in-principle stage to secure it.

Appeal 6006900 concerned a single chalet-style dwelling on land at Rogers Lane within the South Downs National Park. The appeal is useful because it exposes one of the practical limits of permission in principle: PIP decides only location, land use and amount of development. Applicants cannot assume that every benefit they describe can also be legally secured at that stage.

What was the Findon proposal?

The application, reference SDNP/25/04240/PIP, sought permission in principle for the construction of a single chalet-style dwelling on land at Rogers Lane, Findon.

South Downs National Park Authority refused the application. Inspector Alice James dismissed the appeal on 18th September 2026 following a site visit in July.

The Inspector applied the August 2026 NPPF and the South Downs Local Plan, including policies concerned with landscape character, the National Park, the development strategy and sustainable travel.

What can permission in principle actually decide?

The statutory PIP regime is deliberately narrow. At the permission-in-principle stage the decision-maker considers only:

• Location
• Land use
• Amount of development

Other detailed matters are left for a later application for technical details consent.

The government’s Planning Practice Guidance on permission in principle is also clear that planning conditions cannot be attached to PIP and planning obligations cannot be secured at that stage. Obligations may be agreed later at technical details consent where the statutory tests are met.

The self-build point

The appellant indicated that the proposed dwelling would be self-build. The Inspector had regard to the duties in the Self-build and Custom Housebuilding Act 2015 and to South Downs policy supporting housing needs including people wishing to build or commission their own homes.

However, she distinguished the claimed benefit from the mechanism available to secure it. The decision records that a planning obligation could be offered at technical details stage, but that there was no mechanism at PIP stage to secure self-build housing.

The Inspector did not then assign a separate weight to self-build as a secured benefit. In the final balance she gave substantial weight to the general need for more housing, referring to the 4.8-year housing land supply and to NPPF Policy HO7, which includes people wishing to commission or build their own homes where that need is evidenced.

That does not mean self-build can never be secured through planning. It means that an applicant should not assume that the PIP stage can do work which the statutory framework leaves to the later consent.

The same point applied to other matters put forward as benefits, including an orchard, a pond and sustainable construction measures. Those were matters for technical details consent and were neutral in the PIP assessment.

A useful contrast with the recent Bedford decision

There is a wrinkle worth practitioners knowing about. Four days before Findon, another Inspector dealing with Bedford appeal 6011253 treated a PIP description expressly seeking self-build and custom-build dwellings as capable of constraining what could subsequently be approved at technical details consent.

The two decisions therefore take different practical approaches to the importance of self-build wording at PIP. Neither is binding court authority.

The common ground is the national guidance: no planning condition or section 106 obligation can be imposed or secured at the PIP stage itself. The safe practice is therefore to be explicit about what benefit is claimed, why it is material at PIP, and exactly how it will be secured when the technical details consent is sought. Planning Geek’s PIP guidance has been reviewed in light of both decisions.

Landscape harm in the South Downs National Park

The site was an elevated field in a rural and tranquil setting. From the public right of way there were views towards Cissbury Ring, and the Inspector considered that a dwelling would introduce a prominent domestic feature into the open landscape.

Although the site was not physically isolated, it did not read as part of Findon. The proposal would reduce openness, erode the rural character and consolidate domestic development in the landscape.

Substantial weight had to be given to conserving and enhancing the landscape and scenic beauty of the National Park. The Inspector found conflict with the relevant South Downs policies and the NPPF’s protected-landscape policy.

The location was also too car-dependent

Rogers Lane is a narrow, unlit, single-lane road without a footway and is subject to the national speed limit. Reaching Findon’s services on foot or by cycle would involve travelling along the lane and crossing the A24.

The Inspector did not consider the site reasonably accessible by walking, cycling or public transport. Future occupiers would be heavily reliant on private cars, contrary to the development strategy and the Framework’s sustainable-transport approach.

That was a matter the Inspector could assess at PIP because the suitability of the location is one of the three questions the PIP stage is specifically designed to determine.

Housing supply did not rescue the scheme

The South Downs National Park Authority could demonstrate only about a 4.8-year housing land supply. The Inspector therefore gave substantial weight to the delivery of an additional dwelling and to meeting housing needs.

But the site was not physically well related to an existing settlement and the landscape and transport harms were substantial. Those adverse effects outweighed the housing benefit in the final balance.

Appeal 6006900 was dismissed.

What should a PIP applicant take from Findon?

• Keep the PIP stage focused on location, land use and amount
• Do not assume a claimed benefit is legally secured merely because it appears in the application description or supporting statement
• If self-build status matters to the balance, explain the later mechanism intended to secure it
• Remember that landscape and accessibility can still make the location unacceptable at PIP
• Treat recent Inspector decisions on descriptive self-build wording as useful but not binding authority
