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 you 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.

FAQ
There is no single figure, because house extensions are priced from the survey rather than a rate card. At an N16 address the cost follows the structure involved, the access, and how much making good the Victorian and Edwardian terraced construction demands. GS Renovation shows the Hackney Council building control fee on its own line, and Stoke Newington homeowners get that breakdown in writing. You have the written house extensions figure within days of the N16 visit, anywhere in Hackney. As a rough guide, house extensions in London typically starts from roughly £40,000 for a single-storey rear extension and rises with size and specification (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
Far enough to be useful and not so far that the neighbour loses daylight. On your Stoke Newington terrace a deep extension against a shared boundary can significantly overshadow the adjoining property, which is a planning consideration and a common ground for objection. It also darkens the original rear rooms of the house being extended. The depth is usually settled by daylight rather than by the maximum permitted.
It often makes matching them the path of least resistance. Where an adjoining Stoke Newington property has built to a certain depth, an extension of similar proportions is less likely to attract objection and the boundary condition is already established. The existing structure is inspected before anything is built against it, because its foundation and wall condition affect what can be done alongside.
They are usually what makes the space work. Extending the back of your Stoke Newington terrace creates a deep plan whose centre has no external wall, so glazing in the roof over the junction between old and new brings light where windows cannot. The structure supporting a large rooflight is designed for the glass it carries, with deflection limited so the units are not stressed.
By opening it and carrying whatever it supported on a new beam. The rear wall of a Stoke Newington house holds up floors and often the roof, so forming a wide opening into an extension transfers that load onto steel sized for the span. Where insufficient masonry remains at the ends, posts on their own foundations carry it down. The junction between old and new foundations is designed rather than assumed.
Usually, and doing them as one scheme is considerably cheaper than in sequence. A wraparound at a Stoke Newington property shares foundations, a roof and one structural design across both elements, whereas building the rear first and returning for the side means opening the same walls twice. It does make planning permission more likely, which is established at the outset.
