Site constraints 7

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 Named permitted development rights are withdrawn here.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.

Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
