Site constraints 8

Article 4 direction

Former Wycombe Rural District - Poultry Production. Named permitted development rights are withdrawn here.

An Article 4 direction withdraws particular permitted development rights, so work that would normally need no application needs one here. Not every council has published its directions.

Public footpath 25 m away

Matters where it crosses or adjoins the site: obstructing a path without a diversion order is an offence, and work cannot start until the order is confirmed.

Compiled from highway authority data, not the legal definitive map. A few authorities have not published, so no path shown is not proof there is none.

Habitat network: Network Enhancement Zone 2

Where habitat is joined up enough to work as a network. Context, not a constraint on its own.

National landscape 79 m away: Chilterns

Outside the landscape; its setting can still be raised.

Previously an area of outstanding natural beauty, which is still the designation in law. Since 2023 authorities must seek to further its purpose, not merely have regard to it.

Also on the record

Radon affected area, class 2; Inside the Flackwell Heath and Wooburn Green built-up area; Green belt 78 m away: London; 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 listed building at the site · No scheduled monument at the site

Checked on 13 October 2026.

A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
