Site constraints 5

3 Article 4 directions
Residential extensions · Changes of use from commercial, business and service uses to dwellinghouses · Construction of new dwellinghouses in employment areas. Named permitted development rights are withdrawn here.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.
Strategic industrial land
Reserved for industry and logistics.
The London Plan protects strategic industrial locations from other uses; release needs a plan-led process.
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.
