Planning committee
Decided by Kensington and Chelsea Planning Applications Committee on 9 Oct 2025.
Approved unanimously
As officers recommended.
- Officers advised approval because the concealed equipment would protect heritage significance, improve the conservation area and safeguard neighbours’ living conditions.
- Three objections raised concerns about the acoustic enclosure and its size, while Environmental Health and Conservation and Design raised no objections.
- The committee voted unanimously to grant planning permission and listed building consent, adding a condition requiring acoustic enclosure details.
