Single and double storey extensions in Newham. Trusted, professional, 30+ years' hands-on experience.
GS Renovation designs and builds house extensions throughout Newham, mostly on the bay-fronted Victorian and Edwardian terraces of East Ham, Forest Gate and Stratford. Drawing on 30+ years of building in E6, E7, E12, E13, E15 and E16, we handle foundations, steelwork, roofing and the full fit-out as one accountable project.

The classic Newham extension fills in the side return, the narrow alley beside the rear closet wing that these terraces were built with. Roofing over that strip and pushing the back wall out turns a cramped galley kitchen into a wide open-plan kitchen-diner. We dig and pour the foundations, build the walls, and install the steel beams that carry the original rear wall once it comes out, all inspected under building regulations.
A wrap-around extension combines the side return with a rear projection for a much larger ground floor, while a double-storey extension adds a bedroom or bathroom above. On Newham's tighter plots we plan carefully around the boundary and existing drainage, and because the flank and rear walls are usually shared, we sort out any Party Wall Act notices to neighbours in E12 or E13 before we break ground.
Many single-storey rear extensions on Newham terraces fall under permitted development, which means no full planning application, though you may still need a lawful development certificate and prior approval for a larger rear extension. It depends on the size, the height, how much has already been added and whether your street sits within a conservation area, so we always check the position with Newham Council before drawing up the work.
Where a project goes beyond permitted development, for example a double-storey or a wrap-around, or where the property is in a conservation area, a full planning application to Newham Council is required. Either route, the structure itself is controlled by building regulations, with building control inspecting foundations, steel and insulation. We guide you through both consents so an E6 or E7 extension is signed off correctly from footings to finish.
Newham homeowners choose GS Renovation because one team takes the extension from foundations to final decoration, including the engineer's steelwork, the Party Wall notices and the building control inspections. With 30+ years on the borough's terraces we know the side-return layout, the tight plots and Newham Council's requirements, so you deal with a single contractor throughout.
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!
