Planning committee

Decided by Kensington and Chelsea Planning Applications Committee on 23 Jun 2026.

Approved

As officers recommended.

  • Officers advised approval because the works would protect the listed building and have negligible conservation-area impact.
  • Eight letters opposed the planning application, raising concerns about use, residential conversion, pupils, traffic and heritage.
  • The committee granted planning permission by majority, with the listed conditions; listed building consent was also granted.

Site constraints 9

Kensington Square 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 Named permitted development rights are withdrawn here.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.

Checked on 6 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.
