Kilburn is known for red-brick mansion blocks and purpose-built period flats, but its side streets also hold Victorian terraces with room to grow. GS Renovation designs and builds extensions across NW6, and with 30+ years of experience we handle foundations, steelwork, roofs and fit-out, while guiding you through what Brent Council will and will not allow.
Rear and Side-Return Extensions in Kilburn
On Kilburn's Victorian terraces the most popular projects are the rear and side-return extension, which fill the narrow gap beside the closet wing to widen a cramped kitchen into an open-plan family space. We dig and pour the foundations, build the walls, install the steel that carries the original rear wall and lay a flat or pitched roof with rooflights to pull daylight deep into the plan.
Whether your extension is permitted development or needs a full planning application depends on the property. Many Kilburn terraces can extend to the rear under permitted development rights, but flats do not have those rights, and a home in a conservation area or with earlier extensions usually needs planning permission from Brent Council. We check your address first, then submit the right application and handle any party wall notices with your neighbours.
Double-Storey and Wrap-Around Extensions in Kilburn
Where a Kilburn terrace has a generous plot, a wrap-around extension combines the rear and side-return into one larger footprint, and a double-storey scheme adds a bedroom or en-suite above. These larger builds usually mean deeper foundations, more steelwork and careful matching of the red brick and detailing so the addition sits comfortably against the Victorian original. We manage the structural design and the aesthetics together.
A two-storey or wrap-around extension almost always needs planning permission from Brent Council rather than permitted development, and because the flank and rear walls are usually shared, the Party Wall Act applies and notices go to the adjoining owners. Building regulations govern the foundations, the steel beams, the insulation and the fire separation. We coordinate the planning, the party wall awards and the building control inspections so the whole project runs to one programme.
