Site constraints 4

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.

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

Inside the Brookmans Park built-up area; the 1970s provisional farmland map 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

Checked on 11 September 2026. Historic England, the Environment Agency, Natural England and council datasets, Open Government Licence. A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
