Site constraints 10

Green belt: London

Inappropriate development needs very special circumstances.

Green belt policy allows a short list of exceptions, such as limited extensions and replacement buildings. Anything else needs very special circumstances that clearly outweigh the harm. Some green belt land can count as grey belt, where it does not strongly serve the green belt's purposes. The council decides this in its green belt assessment or on each application, so we do not mark it here.

Read the government guidance ↗

Kent Downs National Landscape

Great weight to conserving the landscape; major development restricted.

Previously an area of outstanding natural beauty, which is still the designation in law. Since 2023 authorities must seek to further its purpose, not merely have regard to it.

Registered park or garden 35 m away: The Japanese Garden, Bitchet Wood

Its setting is a consideration for work nearby.

Registered parks and gardens, battlefields, world heritage sites and protected wrecks are designated heritage assets: harm needs clear and convincing justification.

Historic England ↗

Habitat network: Network Enhancement Zone 1

Where habitat is joined up enough to work as a network. Context, not a constraint on its own.

Also on the record

Radon affected area, class 4; 1 listed building within 150 m; SSSI 394 m away: One Tree Hill and Bitchet Common SSSI; Inside the Bitchet Green built-up area; Open access land 29 m away: Access Land - Combined Open Country, Registered Common Land and Section 16 Dedicated Land. MoD Byelaw, Section 28 Exclusions, Racecourses and Aerodromes and ECP Margin have been removed.; Natural England's Provisional ALC map (1:250,000, 1970s) had this area as grade 3, but it predates the buildings here and the current map does not class it as farmland.
