Site constraints 11

49 listed buildings within 150 m of the postcode pin
Nearest: 40, Holland Park W11, Grade II, the postcode pin is inside its outline · 49 Grade II
The site itself is not listed. 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.

Historic England ↗
Holland Park 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 - No 100. Named permitted development rights are withdrawn here.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
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.
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 ↗
Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Registered park or garden about 82 m away: Holland 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.
Historic England ↗
Also on the record
National infrastructure project about 1892 m away: Thames Tideway Tunnel; Inside the Kensington and Chelsea built-up area; Public transport access: PTAL 5 (very good), TfL 2023, for the 100 m square; Metropolitan Open Land about 82 m away.
Not affected
Outside flood zones 2 and 3 · Not green belt · No scheduled monument at the site

Checked on 16 October 2026. The pin for this application is the centre of its postcode rather than the building, so distances to nearby designations are measured from the postcode and can be out by the width of the postcode area.

A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
