Site constraints 4

1 listed building within 150 m
Nearest: Grendon Hall, Grade II, 8 m away
The site itself is not listed. Listed building consent is needed for work that affects the special interest of a listed building, inside or out, on top of planning permission. Setting can be a consideration for buildings nearby; there is no fixed radius.
Historic England ↗
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
Inside the Edgcott 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 · Not green belt · No scheduled monument at the site

Checked on 6 October 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.
