Site constraints 10

Grade II listed: 10 and 12, Cavendish Avenue Nw8
List entry 1066332 · The pin is inside its outline · 31 more listed buildings within 150 m (31 Grade II)
Listed building consent is needed for work that affects the special interest of a listed building, inside or out, on top of planning permission. Setting can be a consideration for buildings nearby; there is no fixed radius.
Show the other 31 with distances
Historic England ↗
St John's Wood 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
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 Named permitted development rights are withdrawn here.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 ↗
Local nature reserve 151 m away: St John's Wood Church Grounds
Work nearby can need a habitats assessment.
Harm to a protected site is only accepted where there is no alternative and an overriding public interest.
Protected tree 9 m away: W227_T1, order W227
3 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.
