Planning committee
Decided by Kensington and Chelsea Planning Applications Committee on 8 Sept 2026. The council has not yet issued its decision notice.
Approved unanimously
As officers recommended.
- Officers advised approval because the basement would remain within 50% garden coverage and construction impacts could be controlled.
- Residents objected over construction disturbance, traffic, overdevelopment, basement size and uncertainty about the staircase proposal.
- The committee unanimously granted permission with the conditions in section 9.
