House extensions on Brondesbury villas inside mapped lines
Two Brent conservation areas, Brondesbury and Mapesbury, both take in parts of Mapesbury Road, and streets around them can fall outside either. An extension on a Brondesbury villa therefore starts with the rear wall, garden and designation of that plot. The Mapesbury guide draws attention to front boundary piers, while rear gardens hold the work itself. We record brickwork, existing additions and drainage before a footprint is drawn.
Brent states that its residential conservation areas carry Article 4 directions, so the approval route for a Brondesbury rear addition, window or roof depends on a mapped line. Inside the designated streets, a house on designated land does not rely on permitted development for a roof or rear enlargement in the same way as a house outside it. Planning, Building Regulations approval and Party Wall etc. Act notices remain separate. In a divided villa, freeholder consent sits beside them. The exact address is plotted first.
Skips, scaffold and stored materials on a Brondesbury street must respect front boundaries that Article 4 can also control. Widening a gateway is no shortcut. A highway licence is needed where Brent controls the footway. Spoil from a rear dig often travels through the house, so halls and original tiles are protected. Neighbouring gardens are photographed before excavation.
Start with the exact Brondesbury address, tenure and photographs of the rear elevation, garden and front boundary. Any earlier planning decisions help fix the approval route. Hampstead Renovations then prepares a written scope covering survey, approvals, groundworks and construction. The extension is built in-house, with original fabric distinguished from new work in the file.
