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.

Also on the record

2 listed buildings within 150 m; Inside the Bovingdon built-up area; the 1970s provisional farmland map had this area as grade 2, but it predates the buildings here and the current map does not class it as farmland.
