Single and double storey extensions in Bethnal Green. Trusted, professional, 30+ years' hands-on experience.
GS Renovation designs and builds extensions across Bethnal Green, adding space to the bay-fronted Victorian and Edwardian terraces that define E2. With over 30 years of building experience in Tower Hamlets, we handle everything from foundations and steel to the final fit-out, turning tight rear plots and side returns into bright, usable rooms.

The most common Bethnal Green extension fills in the side return next to the closet wing and pushes out at the rear, creating an open-plan kitchen-diner across the back of the house. We dig and pour foundations to suit the ground and any nearby trees, build the walls, install the steel that carries the original rear wall, and form a roof, often with rooflights, to flood the deeper plan with light.
Whether the work is permitted development or needs a full planning application depends on your property. Many single-storey rear extensions in E2 fall under permitted development, but Tower Hamlets Council has designated conservation areas and there are Article 4 restrictions in parts of the borough, which can remove those rights. We check your address, advise honestly on the route, and prepare the drawings and applications so the extension is approved before we build.
Where the plot allows, we add a storey above a rear or side-return extension, gaining a bedroom or a bathroom without losing garden. On a Victorian terrace this means matching the brick and detailing, tying the new structure into the existing party walls, and sizing steel to carry the extra floor. Foundations may need to go deeper to take the added load, and we set all of this out with your engineer at the start.
Because a double storey extension usually alters shared walls and sits close to the boundary, the Party Wall Act nearly always applies, and we serve notices on your neighbours early to keep the programme moving. Almost every extension in Bethnal Green also brings your home closer to Victoria Park or the Docklands lifestyle families want, so we finish to a high standard, from plastering and joinery to the plumbing, electrics and decoration.
Homeowners in Bethnal Green choose GS Renovation for extensions because one team handles the planning route, the groundworks, the steel and the finish. We know how E2 terraces are built, how Tower Hamlets Council assesses applications, and how to manage party wall matters with close neighbours. Thirty years in East London means fewer surprises and a build that lasts.
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!

Many single-storey rear extensions in Bethnal Green fall under permitted development, but side returns, double-storey extensions and work in conservation areas usually need full planning permission. We assess your property and manage both the planning application and building control.
Yes. A large share of Bethnal Green's homes are Victorian and Edwardian terraced properties, and we renovate them regularly. We plan each house extensions around their particular characteristics, such as solid brick walls, rear closet wings, side returns and original period features, so the result suits the building and meets building control.
It depends on the property and its location in E2. Many single-storey rear extensions are permitted development, but if you are in a Tower Hamlets conservation area, under an Article 4 direction, or planning a larger or double storey build, you will likely need a full planning application. We check your address against the council's rules and handle whichever route applies before any groundworks begin.
We do. GS Renovation covers all of Bethnal Green and the E2 area and the wider East London. Call 07472 424 226 and we will confirm we work on your road.
