Site constraints 5

Article 4 direction
Dwellinghouses (C3) to small HMOs (C4) - borough-wide Article 4 Direction. Named permitted development rights are withdrawn here.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: 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.
