The Mickleham grey belt appeal has secured permission in principle for one new home in the Surrey Hills after revised national policy changed the Green Belt dispute. Mole Valley District Council had refused the scheme.
Inspector John Morrison allowed appeal 6010634 on 27th October 2026 for land at The Garden House, School Lane, Mickleham, near Dorking. The appeal concerned the location, land use and amount of development, not the detailed design of a house.
I would keep the two issues separate here. The August 2026 National Planning Policy Framework revision meant the proposal was no longer inappropriate Green Belt development, but its effect on the protected landscape still required a separate assessment.
Why the Mickleham grey belt assessment changed
The Council had initially treated the proposed house as inappropriate Green Belt development because of potential harm to the Surrey Hills National Landscape. The Inspector’s report records that the earlier national policy approach relied on a footnote which no longer formed part of the grey belt assessment after the revised Framework and new Housing Delivery Test results.
As a result, the main parties agreed that the proposal would not be inappropriate development in the Green Belt. The Mickleham grey belt decision did not, however, make landscape objections disappear. A statutory duty to further the purpose of conserving and enhancing the natural beauty of National Landscapes continued to apply.
That distinction is a useful warning against reading the revised grey belt guidance as a guarantee of permission. The Green Belt classification and the effect of building on a nationally protected landscape are different questions. Resolving one does not necessarily resolve the other.
An elevated site at the village edge
The appeal land forms part of the curtilage of The Garden House, but its size and open character gave it something of the appearance of a paddock. It is in an elevated valley-side position, with dense woodland behind it. The Surrey Hills National Landscape is valued for its hills, long views, woodland, chalk downland, farmland, historic settlements and tranquillity.
The Mickleham grey belt appeal therefore presented a genuine landscape issue. The plot was not described as visually invisible or devoid of countryside character. It could be seen within the landscape, and that landscape formed part of the qualities the designation is intended to protect.
Equally important was the immediate setting. The land lies beside established built development within and around Mickleham, where buildings of different scales already influence the local scene. Woodland to the rear provides substantial containment when the site is viewed from the wider landscape.
The Inspector was required to consider the Surrey Hills National Landscape as a whole, not simply whether one house would be noticeable from the closest viewpoint. The established village edge and the extent of woodland were central to that judgement.
Why the Inspector allowed permission in principle
The site visit was carried out by appeal planning officer Finlay Bradford, who prepared a recommendation for Inspector Morrison. Bradford reasoned that one dwelling could be designed and positioned to relate to nearby development while avoiding harm to the special landscape qualities.
The report says the Council would control the final design and siting at the later consent stage. Bradford concluded there was a real prospect that the development of one dwelling as applied for has the capability to not cause harm

Inspector Morrison considered the submitted evidence and his representative’s report, accepted the recommendation and allowed the Mickleham grey belt appeal. The decision found that the principle of one home in that location could be consistent with policy EN8 of the Mole Valley Local Plan 2020 to 2039, which protects the character, appearance and setting of the National Landscape.
The decision does not establish a general right to build on garden paddocks inside protected landscapes. It rests on the relationship with existing development, the limited number of homes and the ability to manage detailed impacts at the second stage.
What permission in principle actually authorises
This was a permission-in-principle appeal, rather than a full planning appeal for a fixed set of house drawings. At the first stage, decision-makers assess only the location, land use and amount of housing-led development. Technical details consent is still required before a home can be built under this route.
For the Mickleham grey belt proposal, that second stage will matter. The final siting, massing, appearance, access, landscaping and other relevant technical details must be scrutinised within the limits of the legislation and the permission in principle. Nothing in the appeal letter fixes an approved house design.
This also explains why the Inspector could allow the appeal without knowing all the detail. The question was whether there was a reasonable prospect that a single dwelling could be designed to conserve the special qualities of the landscape, not whether a particular architectural scheme had already achieved that aim.
Readers preparing their own cases should not confuse the two stages. A positive first-stage decision does not remove the need to produce convincing design and environmental evidence when technical details are submitted. For landscape-sensitive sites, a proportionate landscape and visual impact assessment may help establish how a proposal fits its setting.
An earlier Green Belt decision did not decide this case
The report referred to another appeal, 6002245, apparently concerned with Green Belt matters. It did not treat that earlier decision as controlling the new case because the revised national policy had changed what was determinative. The earlier decision’s outcome was not re-decided by this Inspector.
The Mickleham grey belt result is consequently important for the date of the policy framework applied. Planning arguments assembled before a material national policy revision may need to be revisited, particularly where a refusal depended upon wording that has since changed.
Planning Geek’s comparison of the 2024 and 2026 NPPF provides wider context, but the particular grey belt definition, any protected landscape designation and the relevant statutory duties all need examination for each application.
What the ruling means for other sites
The lesson from Mickleham is not that every grey belt plot within a National Landscape is now suitable for housing. The case demonstrates that the question of inappropriate Green Belt development may have a different answer under the revised 2026 framework, while landscape protection continues to have real force.
For applicants, the material questions include whether a proposal can sit naturally against existing buildings, how far woodland or topography actually contains views, and whether a credible design could avoid harm to identified landscape qualities. The absence of detailed drawings at permission-in-principle stage does not eliminate the need to demonstrate a realistic prospect of an acceptable scheme.
For councils, the Mickleham grey belt outcome underlines the importance of using the operative national policy rather than repeating an earlier refusal rationale. It also illustrates why the surviving statutory landscape duty should be addressed openly instead of assuming that Green Belt arguments settle every planning issue.
Ultimately the Inspector allowed one dwelling in principle. The future home, if pursued, still needs technical details consent, and the character of the Surrey Hills remains an important consideration.
