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 you 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.

FAQ
Not by much, and not because of the postcode. What raises a house extensions figure here is the housing rather than the location: solid-wall Victorian terraces with original chimney breasts and suspended timber floors take more making good than a modern estate. Access and parking around E2 affect the labour line too. GS Renovation prices the property in front of it rather than applying a Bethnal Green or East London multiplier. Ring 07472 424 226 and GS Renovation will explain what actually moves the figure at E2. 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.
Faster than most people assume, provided the survey is done early. The lead time on house extensions at an E2 property is usually approvals and materials rather than labour, so GS Renovation starts both as soon as the Bethnal Green scope is signed off. Seasonal demand across Tower Hamlets does move it. Email info@gsrenovationltd.co.uk for the current position on late Victorian and Edwardian properties. The E2 survey is free and there is no obligation afterwards in Bethnal Green.
Over 30 years of hands-on experience sits behind every judgement made on your E2 site. That is our founder's, and it shows in how house extensions are scoped in late Victorian and Edwardian housing before anything is committed. GS Renovation is fully insured, handles Tower Hamlets Council approvals and leaves the Bethnal Green site clean each day. Ring 07472 424 226 and speak to the people who will actually do the Tower Hamlets work. Ask to meet the named manager beforehand.
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 permission. We assess your E2 property and manage both the Tower Hamlets Council application and building control.
Usually earlier alterations that were never done properly. House extensions at an E2 property of that age regularly uncovers removed structure, notched joists or wiring that predates any certificate, and each is costed and agreed before we continue. GS Renovation names the likely candidates at the Bethnal Green survey. Tower Hamlets Council is notified where a change affects approved work. Ask on 07472 424 226 what house extensions commonly uncovers at an E2 address of that sort of age.
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.
Almost certainly. The house extensions patch extends well beyond Bethnal Green and the E2 area, and what matters is whether GS Renovation can survey the property, run the programme and return for aftercare properly. Most of Tower Hamlets and the surrounding East London qualifies. Email info@gsrenovationltd.co.uk with the address and we will give you a straight answer. Nothing is owed for the E2 visit either way. Snagging afterwards is handled by exactly the same team that actually built it.
