Planning committee
Decided by Barnet Planning Committee on 21 Apr 2026.
Refused
Against officer advice: officers had recommended approval.
- Officers advised approval because the basement was considered acceptable in character terms and would not harm neighbours, trees or flood risk.
- Objectors raised concerns about overdevelopment, heritage harm, flooding, ground movement, trees and construction safety.
- The committee refused after casting votes, citing the basement’s scale, overdevelopment and harm to the locally listed building and conservation area.
