Site constraints 5
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.
Habitat network: Network Enhancement Zone 2
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; Inside the Tatsfield built-up area; Priority habitat about 45 m away: Deciduous woodland.
Not affected
Outside flood zones 2 and 3 · No scheduled monument at the site
