Planning committee
Decided by Kensington and Chelsea Planning Applications Committee on 6 Oct 2026.
Refused
Against officer advice: officers had recommended approval.
- Officers advised approval because the units would preserve the conservation area and protect neighbours’ living conditions, subject to conditions.
- Eight objections raised concerns about noise, appearance, visibility, vibration, the shared garden and the retrospective application.
- The committee refused the application against the recommendation, citing harm to the communal garden and conservation area.
