GS Renovation designs and builds extensions throughout Wood Green, working with the bay-fronted Victorian and Edwardian terraces that define N22. Over 30 years we have added rear, side-return and wrap-around extensions to Haringey homes, handling the foundations, steelwork, roof and full fit-out as one accountable project from start to finish.
Side-return extensions on Wood Green terraces
The side return beside the rear closet wing is the classic space to claim on a Wood Green terrace. Filling it in widens a narrow galley kitchen into a proper open-plan kitchen-diner running the full width of the house. We dig and pour the foundations, build the walls, install the steel beams that carry the original rear wall and fit a roof with rooflights to draw daylight deep into the plan.
These terraces sit on tight urban plots, so we plan access, spoil removal and material deliveries carefully around parked cars and neighbouring gardens. Where the extension meets or sits against a shared boundary, party wall matters usually apply, and you serve notice in good time. The finished space is fully fitted, insulated to current standards and signed off by building control.
Planning and permitted development in Haringey
Many single-storey rear extensions in Wood Green fall under permitted development, but that is never a given. If your house has already been extended, sits within a conservation area or you are going to two storeys, a full planning application to Haringey Council is likely to be needed. We assess your property honestly at the outset and tell you which route applies rather than assuming the easy answer.
Whichever route you take, the structural side still needs building regulations approval, and that is separate from planning. We prepare the drawings, deal with Haringey Council where a formal application is required and book the building control inspections for the foundations, steel and drainage. Keeping the two processes distinct means no surprises, no enforcement risk and a build that stands up to scrutiny.
Inspection stages on an extension
An extension is inspected far more often than an internal alteration, and knowing the stages helps you follow the programme. The first visit comes at excavation, before any concrete goes in, so the inspector can see the foundation depth and the ground it will bear on. The second covers the concrete itself, then the damp proof course and the oversite before a floor is laid over the top of them.
After that come drainage, which is tested and inspected while it is still open, then the structural steel and its bearings, then insulation and the roof before either is covered. A final visit follows completion and releases the certificate. In Haringey the drainage and foundation visits are the ones most often missed by people managing their own build, and both are very hard to demonstrate once buried. We book each visit as the work reaches it and keep the inspector's records with the drawings, so nothing has to be reconstructed later.
