The council must give weight to preserving or enhancing the area's character and appearance. Not every council has published its boundaries as open data.
Council document ↗
3 Article 4 directions
Article 4 - No 41 · Article 4 - No 68 · Article 4 - No 100. Named permitted development rights are withdrawn here.

Tree preservation order
Consent is needed before work on protected trees.
Not every council has published its orders as open data, so no order shown is not proof there is none.
Air quality management area: Kensington and Chelsea AQMA
The council has declared the area as failing an air quality objective.
