Site constraints 8

Article 4 direction
Change of use or development that would result in new dwellings (Class MA/ZA). Named permitted development rights are withdrawn here.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.
Locally significant industrial site
A borough-level industrial site.
Boroughs protect these sites for industrial and related uses.
Air quality management area: Hounslow 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.
