GS Renovation designs and builds extensions across Teddington, working with the bay-fronted Victorian and Edwardian terraces, closet wings and side returns that define TW11. With more than 30 years in Richmond upon Thames, we take rear, side-return and wrap-around projects from foundations and steelwork through to the final fit-out, all under Richmond Council building control.
Side-return and rear extensions in Teddington
The classic Teddington extension fills the side return, the narrow strip of yard beside the closet wing, to widen a cramped Victorian kitchen into a proper open-plan space. We dig and pour foundations to suit the local ground, form the new walls and install a steel beam across the old rear opening so the room reads as one. A wrap-around scheme continues past the closet wing to add real depth, with rooflights bringing daylight into the middle of the plan.
Because these terraces sit on tight plots close to their neighbours, we plan the build to keep disruption down, protecting the party wall and managing access along a narrow TW11 street. Double-storey rear extensions add a bedroom or bathroom above the new ground floor, which means heavier foundations and steel again sized by a structural engineer. We handle the groundworks, roofing, glazing and full internal fit-out so you deal with one team throughout.
Planning permission and building regs in TW11
Some Teddington extensions fall under permitted development, while others need a full planning application to Richmond Council, and which route applies depends on the property. Size, height, how much you have already extended and whether the home sits within a conservation area or is listed all change the answer. We assess your terrace honestly, tell you which path fits and prepare the drawings, rather than assuming every scheme can be built under permitted development rights.
Whichever planning route applies, the structural work itself is governed by building regulations, so the foundations, steel beams, drainage, insulation and fire safety are all inspected and signed off by building control. Where the extension touches a shared boundary or party wall, you serve the correct notices too. Keeping planning and building regs clearly separate means no surprises, a lawful build and a finished extension that adds lasting value to a Teddington home.
