Site constraints 9

Dulwich Village 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 ↗
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.

Habitat network: Other Priority Habitats - NEZ
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Registered park or garden 62 m away: Dulwich Park
Its setting is a consideration for work nearby.
Registered parks and gardens, battlefields, world heritage sites and protected wrecks are designated heritage assets: harm needs clear and convincing justification.
