Site constraints 10

Harefield Village conservation area
Demolition needs planning permission and permitted development is restricted.
The council must give weight to preserving or enhancing the area's character and appearance. Not every council has published its boundaries as open data.
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 Named permitted development rights are withdrawn here.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.
Also on the record
Radon affected area, class 2; 3 listed buildings within 150 m of the postcode pin; SSSI about 498 m away: Harefield Pit SSSI; Inside the Hillingdon built-up area; Public transport access: PTAL 1b (very poor), TfL 2023, for the 100 m square; National infrastructure project about 1993 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 3, but it predates the buildings here and the current map does not class it as farmland.
