Site constraints 7

Sunray Estate conservation area
Demolition needs planning permission and permitted development is restricted.
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 ↗
Article 4 direction
The Sunray Estate. Named permitted development rights are withdrawn here.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.
Tree preservation order: Area bounded by Denmark Hill, Sunray Avenue, Red Post Hill and Casino Avenue.
Consent is needed before work on protected trees. A single protected tree within 15 m, nearest 14 m.
Not every council has published its orders as open data, so no order shown is not proof there is none.
Air quality management area: Southwark 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.
