Planning committee

Decided by Kensington and Chelsea Planning Applications Committee on 21 Jul 2026.

Refused unanimously

Against officer advice: officers had recommended approval.

  • Officers advised approval because the design, living conditions, transport, basement and flood impacts were acceptable subject to conditions.
  • Objectors raised concerns about design, construction disruption, basement works, trees, refuse storage, overdevelopment and neighbours’ daylight.
  • The committee unanimously refused permission, citing the missing draft construction traffic plan and harm to the conservation area.

Site constraints 8

Chelsea 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 Named permitted development rights are withdrawn here.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 ↗
11 listed buildings within 150 m of the postcode pin
Nearest: 24-47, Halsey Street Sw3, Grade II, about 6 m from the postcode pin · 1 Grade II*, 10 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 ↗
National infrastructure project about 730 m away: Thames Tideway Tunnel
The site is about 730 m from the project boundary. Waste water treatment, decided. The project page says whether consent was granted. Also within 2 km: London Strategic Heat Main Project (at pre-application, about 236 m).
Nationally significant infrastructure projects (power stations, electricity lines, pipelines, major roads and railways, harbours, airports and reservoirs) are consented by a Secretary of State under the Planning Act 2008, after an examination by the Planning Inspectorate, rather than by the council. The boundary is the one the Inspectorate consults on and can change as the scheme does. Projects are shown within 2 km of the site.

Also on the record
Inside the Kensington and Chelsea built-up area; Public transport access: PTAL 6a (excellent), TfL 2023, for the 100 m square.
Not affected
Outside flood zones 2 and 3 · Not green belt · No scheduled monument at the site

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.
