Rear and side-return extensions for Kilburn houses

Extending a Kilburn house joins new work to older fabric that may have been altered many times. Opening a rear wall or side return changes load paths, and the party wall with the neighbour may be affected. New drainage can lengthen existing runs or meet a shared connection. Measured levels, available records and the defects already visible guide the design, with structural calculations and opening-up used where the risk warrants them.

A Kilburn extension may need planning permission, and the application goes to the authority for the exact address, which may be Brent, Camden or Westminster. The adopted Kilburn Neighbourhood Plan sits alongside the borough plans within its boundary, but it grants no permission itself. Building Regulations approval can be needed even when planning is not. Work to a party wall, or excavation close to a neighbour’s foundations, may fall under the Party Wall etc. Act. In a ground-floor flat, the lease may also require freeholder consent.

In a Kilburn terrace, a rear extension may have no side access, so every brick, steel and bag of spoil passes through the house. Floors and hallways are protected along that route. Where the house is shared, the route is agreed with the freeholder and escape routes stay clear. A skip or grab lorry at the front needs the correct licence or suspension from the highway authority for that road. On a red route, that authority is Transport for London.

Bring whatever you have: the exact address, photographs of the rear elevation and garden, any drawings, and the planning history if known. Describe the room you want rather than a fixed footprint. Hampstead Renovations reviews the levels, drainage and structure, then sets out a written scope stating what has been verified and what remains provisional. Once that scope is agreed, the extension is built in-house, and steelwork, drainage and insulation are photographed before being covered.
