Site constraints 7

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 ↗
Public footpath 17 m away
Matters where it crosses or adjoins the site: obstructing a path without a diversion order is an offence, and work cannot start until the order is confirmed.
Compiled from highway authority data, not the legal definitive map. A few authorities have not published, so no path shown is not proof there is none.
Habitat network: Lowland meadows
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 2; Priority habitat 3 m away: Deciduous woodland; Inside the Cookham built-up area; 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.
Not affected
Outside flood zones 2 and 3 · No listed building at the site · No scheduled monument at the site
