GS Renovation designs and builds extensions throughout Greenwich, from side-return infills on Victorian terraces in Charlton to rear additions on Eltham and Woolwich family homes. With over 30 years across SE3, SE7, SE9, SE10 and SE18, we handle foundations, steel, roofing and fit-out, and guide you through whether the work is permitted development or needs planning.
Rear and side-return extensions in Greenwich
The classic Greenwich extension opens up the back of a Victorian terrace by filling in the side return and pushing out to the rear. These SE7 and SE18 terraces have a narrow closet wing and an awkward L-shaped kitchen, so squaring off the footprint transforms the ground floor. We dig and pour foundations to suit the ground, then carry the existing wall on steel to create one open kitchen-diner.
Double storey and wrap-around extensions suit the larger plots found around Blackheath and the leafier streets of Eltham. Whatever the shape, we manage the groundworks, the steel, the new roof and the drainage as one job. Because homes near Greenwich Park often sit in conservation areas, we design to respect the street and prepare the drawings the Royal Borough of Greenwich will want to see.
Planning and permitted development in Greenwich
Not every extension in Greenwich needs planning permission. Many single storey rear extensions fall under permitted development, but that right is often removed or restricted in conservation areas and never applies to listed buildings, both common in SE3 and SE10. We assess your property early, tell you honestly whether you can build under permitted development or must submit a full application to the council, and handle the paperwork either way.
Whichever route applies, the structural side still needs building regulations approval, with building control inspecting the foundations, steel and drainage as work proceeds. Where your extension sits against a neighbour's boundary or a shared wall, the Party Wall Act comes into play too. We coordinate the planning, the building control so nothing stalls the programme on site in Woolwich or Charlton.
- Party Wall Act notices for excavation near a neighbour's wall
- Single and double storey extensions
- Building control inspections at foundation, damp course and steel stages
- Roof works and structural alterations at roof level
- Scaffolding, site set-up and safe access on tight London plots
