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. 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.

National infrastructure project about 173 m away: M4 Junctions 3 to 12 Smart Motorway

The site is about 173 m from the project boundary. Highway, decided. The project page says whether consent was granted.

Nationally significant infrastructure projects (power stations, electricity lines, pipelines, major roads and railways, harbours, airports and reservoirs) are consented by a Secretary of State under the Planning Act 2008, after an examination by the Planning Inspectorate, rather than by the council. The boundary is the one the Inspectorate consults on and can change as the scheme does. Projects are shown within 2 km of the site.

Also on the record

Inside the Dorney Reach built-up area; Natural England's Provisional ALC map (1:250,000, 1970s) had this area as grade 2, 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

Checked on 6 October 2026. The pin for this application is the centre of its postcode rather than the building, so distances to nearby designations are measured from the postcode and can be out by the width of the postcode area. Historic England, the Environment Agency, Natural England, the Planning Inspectorate 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.
