Site constraints 8

Article 4 direction
Residential extensions. Named permitted development rights are withdrawn here.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 ↗
National infrastructure project 398 m away: M4 Junctions 3 to 12 Smart Motorway
The site is 398 m from the project boundary. Highway, decided. The project page says whether consent was granted. Also within 2 km: Expansion of Heathrow Airport (Third Runway) (at pre-application, 316 m).
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.
Planning Inspectorate project page ↗
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 1b (very poor), TfL 2023, for the 100 m square; Green belt 32 m away: London; Priority habitat 31 m away: No main habitat but additional habitats present.
Not affected
Outside flood zones 2 and 3 · No listed building at the site · No scheduled monument at the site

Checked on 6 October 2026.

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