Site constraints 10

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 Named permitted development rights are withdrawn here.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.

Archaeological priority area

An assessment or field evaluation may be asked for before ground works.

The council or Historic England considers archaeology likely here. A desk-based assessment, and sometimes trial trenching, can be asked for with the application.

SSSI about 86 m away: Mid Colne Valley SSSI

Natural England may need consulting, depending on what is proposed.

Sites of special scientific interest are the best wildlife and geological sites in the country. Development likely to harm one is rarely permitted.

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

Conservation area about 26 m away: Widewater Lock; Radon affected area, class 2; Inside the Hillingdon built-up area; Public transport access: PTAL 1a (very poor), TfL 2023, for the 100 m square; National infrastructure project about 1583 m away: Expansion of Heathrow Airport (Third Runway), at pre-application; Green belt about 74 m away: London.

Outside flood zones 2 and 3 · No scheduled monument at the site
