Historic England ↗

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 Expansion Zone

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; Inside the Great Amwell built-up area; Priority habitat 15 m away: Deciduous woodland; 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 scheduled monument at the site
