For more than 30 years GS Renovation has extended homes across Wallington, from the Edwardian family houses near Beddington Park to the terraces in the SM6 streets. Whether you want a rear kitchen extension, a side-return infill or a double-storey addition, we handle the foundations, the steelwork, the roof and the full fit-out as one project.
Rear And Side-Return Extensions In Wallington
The side return on a Wallington terrace, that narrow strip of yard beside the rear closet wing, is often wasted space. Filling it in and extending across the back of the house creates the wide, open kitchen-diner most families want. We tie the new structure into the existing rear wall, insert a steel beam where the old external wall comes out, and match the brickwork so the extension sits naturally against the period house.
Every extension starts below ground. We dig and pour foundations to the depth building control requires, allowing for any nearby trees around Wallington's leafier roads, then build up in blockwork and brick. Steel beams carry the openings and the roof, which we finish as a pitched or flat structure with rooflights to bring daylight deep into the plan. Drainage, insulation and the internal fit-out all follow, managed by the same team from start to finish.
Planning And Permitted Development In Wallington
Some extensions in Wallington fall under permitted development and do not need a planning application, while others require full permission from Sutton Council. It depends on the size, height and position of what you are building, and whether your property sits in a conservation area or has had permitted development rights removed. We assess your home early, advise which route applies, and prepare and submit the drawings to the council where planning permission is needed.
Separate from planning, every extension must meet building regulations, and building control inspects the foundations, the steelwork, the insulation and the drainage as the work proceeds. On the terraces, a rear or side extension usually sits against a shared boundary, so party wall notices to your neighbours often come into play too. We coordinate all three, planning where needed, building control and party wall matters, so nothing holds the project up.
