Site constraints 8

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.

Chilterns 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.
Article 4 direction
Whole District excluding the Town of Chesham - Poultry production.. Named permitted development rights are withdrawn here.
An Article 4 direction withdraws particular permitted development rights, so work that would normally need no application needs one here. Not every council has published its directions.
Habitat network: Other Priority Habitats - NEZ
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 2 m away: Deciduous woodland; Inside the Chalfont St Giles 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
