Refused on 14 Oct 2025 · Last checked 24 Oct 2026
Planning committee
Decided by Kensington and Chelsea Planning Applications Committee on 9 Oct 2025.
Refused unanimously
Against officer advice: officers had recommended approval.
- Officers advised approval because the modest extension would preserve the building and conservation area, with nearby living conditions safeguarded.
- Objectors raised concerns about the extension’s character, outdoor space, privacy, enclosure, sunlight, noise and construction effects.
- The committee voted unanimously to refuse because the extension was not subordinate and would harm existing outdoor amenity space.
