Site constraints 5

Article 4 direction
Article 4 Basement Development Permitted Rights Removed. Named permitted development rights are withdrawn here.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: Westminster 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.
Council record ↗
Protected tree 11 m away: W421_T4, order W421
2 protected trees within 15 m. Named in a tree preservation order: work to it, its roots included, needs the council's consent first.
Root protection areas reach up to 15 m from a large tree, so an extension or new foundations this close usually needs a tree survey. Only some councils publish their single trees, and a position can be approximate: the order at the council is the definitive record, and no tree shown is not proof there is none.
