GS Renovation designs and builds extensions across Sidcup, where interwar semis and detached houses sit on the generous plots that suit rear and side additions. With over 30 years of experience in DA15 and the Bexley borough, we handle foundations, steelwork, roofing and full fit-out, guiding you through permitted development or a planning application to the council.
Rear and side-return extensions in Sidcup
The wide plots common across Sidcup give real scope for extending, and the most popular projects are single or double storey rear additions that open the back of a 1930s semi into a large kitchen-diner. Side-return and wrap-around extensions make use of the space beside the house, and where the original rear wall comes out we install a steel beam sized by a structural engineer to carry the load above.
We start with proper foundations and groundworks suited to the ground conditions, then build up in brick or block to match the interwar character, tie in the new roof, and complete the internal fit-out. Because a semi shares a boundary and party wall with the neighbour, excavating near that line usually brings the Party Wall Act into play, which we handle for you.
Planning and building control in Bexley
Many single storey rear extensions on Sidcup houses fall under permitted development, meaning no full planning application is required, though this depends on the size, height and whether previous extensions have used up your allowance. Double storey additions, work to the front, or anything affecting the street scene usually needs planning permission from Bexley Council, and we advise which route applies before any drawings are finalised.
Whichever route the property takes, every extension must satisfy building regulations, and Bexley Council building control inspects the foundations, the steelwork, the insulation and the drainage as the work proceeds. We manage the applications, the inspections and the party wall notices together, so you have one team accountable for both the paperwork and the build from start to finish.
