Site constraints 9

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.

Read the government guidance ↗

2 Article 4 directions

Residential extensions · Houses of Multiple Occupation (HMOs). Named permitted development rights are withdrawn here.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.

Air quality management area: Hillingdon AQMA

The council has declared the area as failing an air quality objective.

Schemes that add traffic, parking or combustion plant are assessed against the area's action plan and may need an air quality assessment.

Council record ↗

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 Hillingdon built-up area; Public transport access: PTAL 2 (poor), TfL 2023, for the 100 m square; Priority habitat about 14 m away: Traditional orchard; National infrastructure project about 1231 m away: Expansion of Heathrow Airport (Third Runway), at pre-application; 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
