GS Renovation designs and builds extensions across Chislehurst, adding space to the bay-fronted Victorian and Edwardian terraces and the substantial homes near the common. With over 30 years of building experience in BR7 and across Bromley, we manage the whole project, from foundations and steelwork to the final fit-out.
Side-return extensions in Chislehurst terraces
The side return beside the rear closet wing is often wasted ground in a Chislehurst terrace, a narrow strip that adds surprising width once it is built in. Filling it lets us square off a cramped galley kitchen into a proper kitchen-diner running the full width of the house. The work involves new foundations dug beside the existing wall, a steel beam over the opening, and a roof, usually part glazed to bring light deep into the plan.
A side-return extension often falls within permitted development, but that depends on your property, so it is never a given. Homes in a conservation area, or ones where earlier extensions have used up the allowance, may need a full planning application to Bromley Council. Where the new foundations run along the boundary with your neighbour, the Party Wall Act applies too. We check the planning position first and tell you honestly which route your house needs before we start.
Double storey extensions for Chislehurst homes
The substantial homes near Chislehurst Common often have room to grow both down and up, so we build double storey rear extensions that add a larger kitchen below and an extra bedroom or en-suite above. Deeper foundations carry the extra load, and steel beams tie the new structure back into the original walls. Matching the brick, the bay detailing and the roofline to the existing house matters as much as the space itself in a period street.
A two storey extension is more likely to need planning permission than a modest single storey one, and we handle the application to Bromley Council where it is required. Every extension, whatever its size, must meet building regulations for foundations, structure, insulation and fire safety, inspected as the build progresses. We coordinate the party wall notices, the trades and the fit-out so you deal with one team from the first drawing to the finished rooms.
