GS Renovation designs and builds extensions across Edmonton, from single-storey rear additions to double-storey and wrap-around projects on the Victorian and Edwardian terraces of N9. With more than 30 years in Enfield borough, we handle the groundworks, steelwork, roof and full fit-out, and guide you through whether the work is permitted development or needs planning.
Side-return and rear extensions in Edmonton
The classic Edmonton project fills in the side return, the narrow strip of yard alongside the original rear closet wing, to square off a cramped galley kitchen into a wide, open kitchen-diner. We dig and pour new foundations tied into the existing terrace, build the walls, and install a steel beam where the old external wall comes out so the upper floors stay supported. A glazed roof or rooflights then bring daylight deep into the plan.
Rear extensions push the ground floor out into the garden and suit the generous back plots on many N9 streets. We manage the groundworks, drainage diversions around existing manholes, the structural openings and the roof as one sequence. Because these terraces adjoin neighbours on both sides, a party wall notice is usually needed where we build up to or along the boundary, and we raise that with you before work starts.
Planning and permitted development in Enfield
Not every Edmonton extension needs a planning application. Many single-storey rear extensions fall under permitted development if they stay within the size, height and boundary limits, though those rights can be restricted, so we always check the specific property first. Where a design goes beyond those limits, or where you want a double storey or a wrap-around, we prepare and submit a full application to Enfield Council on your behalf.
Either route, the structure still needs building regulations approval, which is separate from planning and covers the foundations, beams, insulation, drainage and fire safety. We are familiar with how Enfield Council handles applications on N9 terraced streets and design to give you the best chance of approval. Getting the correct consents in place before the diggers arrive keeps the project legal and avoids costly changes once the walls are up.
