Planning committee

Decided by Kensington and Chelsea Planning Applications Committee on 21 Oct 2025.

Refused unanimously

As officers recommended.

No officer report was published for this decision; this summary is from the committee minutes.

  • Officers recommended refusal, finding the proposal would cause less than substantial harm to the conservation area without sufficient public benefit to outweigh it.
  • An objector spoke against the scheme while the applicant spoke in support.
  • The committee unanimously supported the officer's recommendation, agreeing the replacement dwelling would not improve on the existing one in the conservation area.
Read how the committee decided The officers' assessment of harm, the objection and support, and the committee's decision to refuse.

Site constraints 9

The Boltons 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 Named permitted development rights are withdrawn here.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 ↗
National infrastructure project about 602 m away: Thames Tideway Tunnel
The site is about 602 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 1056 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.
Planning Inspectorate project page ↗
Also on the record
Registered park or garden about 129 m away: The Boltons; 6 listed buildings within 150 m of the postcode pin; Inside the Kensington and Chelsea built-up area; Public transport access: PTAL 2 (poor), 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. Historic England, the Environment Agency, Natural England, the Planning Inspectorate, Transport for London (public transport access levels, Powered by TfL Open Data, OGL v3.0, contains OS data © Crown copyright and database right 2025) and council datasets, Open Government Licence. A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
