Four Caterham homes proposed off Waller Lane in Surrey have lost a planning appeal despite meeting a national policy exception for housing near a well-connected station. Inspector Thea L Davis dismissed the appeal on 14th October 2026, finding unacceptable effects on rural character, significant trees and possible hazel dormice habitat.
The scheme would have demolished existing buildings and created four detached homes with associated access on land beside Southwood, between Caterham and Caterham-on-the-Hill. The decision leaves Tandridge District Council’s refusal in place. It grants no permission for the houses, even though the Inspector rejected the Green Belt obstacle.
I would separate those two findings carefully. Being close enough to a qualifying station can remove one policy barrier, but it does not settle whether the design and ecological evidence are acceptable. For neighbours using this wooded lane, the effects on its quiet character and trees remained central to the outcome.
How the Caterham homes met the station test
The Inspector assessed the scheme against the National Planning Policy Framework published on 17th August 2026. Its Green Belt policy GB7(1)(h) provides an exception for residential or mixed-use development where five criteria are met, including proximity to a well-connected station and the relationship with the station or settlement.
Caterham station is a terminus. The submitted schedule indicated two trains an hour leaving for London, which the Inspector accepted met the relevant service definition. The appellant also supplied evidence about the station’s location within a qualifying Travel to Work Area, the geographical area used for the policy’s economic test.
The site was approximately 470 metres from the station, within the policy’s 800-metre walking distance. The council raised Waller Lane’s steep incline and lack of footways, but the Inspector found no substantive evidence that the gradient created significant pedestrian problems. The neighbourhood plan also identified the lane as a vital pedestrian route.
The Caterham homes were physically well-related to the station and settlement. Four dwellings were unlikely to have a noticeable infrastructure effect, and the remaining criteria were satisfied. The proposal was therefore not inappropriate development in the Green Belt, without needing very special circumstances.
That also meant the dispute about whether the land was grey belt did not need deciding for that exception. I would not describe this as an appeal establishing grey belt status. The station route supplied the relevant answer to the Green Belt question.
The wooded lane still mattered
The Inspector described Waller Lane as steep, narrow and enclosed by vegetation, crossing the Green Belt between two urban areas. Buildings were generally screened, with access tracks offset rather than opening direct views into plots. The appeal land retained a rural character despite being near the town.
A widened entrance and shared surfaced drive for the Caterham homes would have opened views towards the proposed houses. Plots one, two and four would have been particularly visible. A cluster of dwellings arranged in that way would conflict with the established development pattern and harm the character of the site and surrounding area.
Three of the four dwellings would be within or against root protection areas of important trees. The submitted tree report indicated that regular pruning would be needed because of the houses’ proximity. The Inspector found that this relationship would increase pressure for removal and negatively affect trees significant to the site.
For the Caterham homes, these were substantive design and landscape objections. Resolving the Green Belt principle did not remove the development plan policies protecting local distinctiveness, wooded hillsides and important trees.
Dormice evidence and biodiversity gain were different issues
The ecological assessment identified possible hazel dormice presence in the wider area and mixed scrub on the site. It recommended no further surveys because the scrub was not expected to be affected. The Inspector nevertheless found insufficient evidence that breeding or resting places and access to shelter would be protected.
The decision did not establish that dormice were present. It found that potential harm could not be ruled out on the evidence provided. The precautionary approach therefore counted against the proposal, notwithstanding modest improvements proposed to the wider wildlife corridor.
Biodiversity net gain was a separate question. The Inspector accepted that the statutory gain requirement could be addressed through measures on the site. That favourable finding did not cure the missing protected-species evidence. A lighting management plan could also have been conditioned, but that did not resolve the wider ecological objection.
Why housing need did not overturn the refusal
Tandridge accepted that it could not demonstrate a five-year housing land supply. The Inspector agreed that there was evidenced unmet need and gave substantial weight to providing four additional homes. The station-related policy also supported development outside a settlement in principle.
However, the benefits of the Caterham homes were substantially outweighed by harm to character, important trees and potential effects on a protected species. In the full official decision, the Inspector explained that clearing the Green Belt test “does not automatically mean that it is acceptable in terms of other planning issues”.
The decision concerns application 2025/1350 and appeal 6008351, brought by Asprey Homes Southern Ltd. Additional information submitted during the appeal did not lead the Inspector to assess an evolved scheme in place of the application documentation. For anyone reconsidering the Caterham homes, my reading is that the layout, tree relationships and ecological evidence need attention together. Proximity to the station alone does not answer those objections.
