Single and double storey extensions in Stoke Newington. Trusted, professional, 30+ years' hands-on experience.
GS Renovation designs and builds extensions across Stoke Newington, adapting the bay-fronted Victorian and Edwardian terraces around Clissold Park for modern family living. With over 30 years of experience in N16 and the surrounding Hackney streets, we handle foundations, steelwork, roofing and full fit-out as one managed project.

The classic Stoke Newington extension fills in the side return, that narrow strip beside the rear closet wing, and pushes back into the garden to create a wide open-plan kitchen-diner. These N16 terraces were built with that awkward L-shaped rear, so infilling it transforms a dark galley kitchen into a bright, sociable space, usually with a steel beam carrying the original wall above and rooflights bringing light deep into the plan.
We start with the groundworks, digging and pouring foundations that account for nearby trees and the clay subsoil common across Hackney. Then comes the structural steel, the brickwork or timber frame, the roof and the glazing, followed by a full fit-out of plumbing, electrics, plastering and decoration. One team runs it from the first dig to the final coat of paint.
Many single-storey rear and side-return extensions in Stoke Newington fall under permitted development, but not all do. Larger projects, double-storey additions, or homes in a conservation area or subject to an Article 4 direction will need a full planning application to Hackney Council. We assess your specific property early, tell you honestly which route applies, and prepare the drawings and submission accordingly.
Structural work within the extension is a building regulations matter, so building control inspects the foundations, the steel and the weatherproofing regardless of the planning route. Because these terraces share walls, extending near or against a boundary usually triggers the Party Wall Act, so we serve notice on the neighbours in good time. Getting planning, building regs and party wall matters lined up from the outset keeps the build moving.
Stoke Newington homeowners choose GS Renovation because we manage the whole extension under one roof, from foundations and steel to the finished kitchen. We know how N16 terraces and their side returns behave, we are straight about planning versus permitted development, and 30+ years across Hackney means tidy, dependable work in an occupied home.
George was brilliant. Lovely bloke, very reasonably priced and a perfectionist to boot. He completed our small kitchen renovation with care and great attention to detail. I've already recommended him to others.
Splendid job on our new kitchen refurb, including new flooring, moving the services, installing RSJ and preparing space for new back doors… George was always friendly, communicative and has an excellent attention to detail, ensuring everything is finished to a high standard.
Giorgio is an excellent and intelligent workman, and with very reasonable prices!… He paid a lot of attention to detail that is not common at all, and the final result was immaculate. Highly recommended!
