Rear and side-return extensions in Camden

The classic Camden project fills the side return of a Victorian terrace in Kentish Town or extends into the rear garden of a townhouse near Regent's Park. We dig and lay foundations to suit the ground and any nearby trees, install the steel beams that carry the existing rear wall, and build up in matching brick before fitting the roof, glazing and services. The result is a bright kitchen-diner that respects the house.

Whether an extension is permitted development or needs a full planning application depends entirely on the property. A modest single-storey rear extension may fall under permitted development, but homes in Camden's conservation areas, and any listed building, usually need planning permission and sometimes listed building consent from Camden Council. We assess your specific address before design so there are no surprises later.

Foundations and party walls across Camden

Camden's period terraces sit on tight plots with shared boundaries, so most extensions here engage the Party Wall Act. Where we excavate near or build off a party wall in NW5 or N19, notice must be served on adjoining owners and a schedule of condition agreed. We build the foundations, damp proofing and drainage correctly for the age of the property and its solid-wall construction.

Above ground we tie the new structure into the original brickwork, form the openings with engineer-designed steel, and weatherproof the roof, whether that is a flat warm roof with rooflights or a pitched roof to match a neighbouring return. Building control inspects the foundations, steel, insulation and drainage at each stage, and we complete the full internal fit-out ready to use.

George was brilliant. Lovely bloke, very reasonably priced and a perfectionist to boot. He completed our small kitchen renovation with care and great attention to detail. I've already recommended him to others.

Splendid job on our new kitchen refurb, including new flooring, moving the services, installing RSJ and preparing space for new back doors… George was always friendly, communicative and has an excellent attention to detail, ensuring everything is finished to a high standard.
