Single and double storey extensions in Ilford. Trusted, professional, 30+ years' hands-on experience.
Ilford's bay-fronted Victorian and Edwardian terraces, with their rear closet wings and side returns, extend beautifully. GS Renovation has spent over 30 years adding space to IG1 homes, from a modest kitchen extension to a full wrap-around. We handle the foundations, the steel, the roof and the fit-out, and we guide you through Redbridge Council's planning rules.

The side return on an Ilford terrace, that narrow strip beside the closet wing, is often dead space. Filling it in and extending to the rear turns a cramped galley kitchen into an open-plan kitchen-diner that runs the full width of the house. We dig and pour the foundations to the required depth, allowing for the mature trees around Valentines Park and Wanstead Park that can affect ground conditions on clay soils.
Steel beams tie the new opening back into the original structure, sized by an engineer and inspected by building control. We build up the walls, form the roof, whether a flat roof with rooflights or a pitched addition, and weather it in before moving inside. Where the extension sits against a neighbour's boundary, which is common on these tightly packed IG1 plots, the Party Wall Act applies and we serve the notices for you.
Many single-storey rear extensions in Ilford fall under permitted development, meaning no full planning application is needed provided you stay within the size, height and materials limits. A double-storey extension, a build close to the front, or work on a property in one of Redbridge's conservation areas usually needs planning permission from Redbridge Council. We assess your specific house first and tell you honestly which route applies before any drawings are commissioned.
Whichever route your extension takes, the building work itself must meet building regulations, covering foundations, structure, insulation, drainage and fire safety, all inspected as we go. We can recommend architects and structural engineers, or work to plans you already hold. From the first trench to the final coat of paint, one GS Renovation team runs the site, so you are not left chasing separate trades across a half-finished IG1 extension.
Homeowners across Ilford and neighbouring Woodford and Wanstead trust GS Renovation because we deliver the whole extension, structure, roof, services and finish, as one accountable job. We know how these IG1 terraces are built, where the load paths run and how Redbridge Council handles planning. Thirty-plus years of local work means fewer surprises and a build that adds real, lasting value.
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!
