Single and double storey extensions in Tower Hamlets. Trusted, professional, 30+ years' hands-on experience.
GS Renovation designs and builds house extensions across Tower Hamlets, working with the Victorian terraces of Bow and Bethnal Green as well as the warehouse-conversion and new-build stock around Wapping and Canary Wharf. With 30+ years across E1, E2, E3 and E14, we take extensions from foundations and steel to full fit-out.

The classic Tower Hamlets extension opens up the rear of a Victorian terrace in Bow or Bethnal Green, filling in the side return and pushing back into the garden to create a bright kitchen-diner. We handle the groundworks and foundations first, checking for the drains and shallow footings common in E3 terraces, then set the steel beams that carry the existing rear wall once the old back addition comes down.
On tighter plots and in conservation areas near Victoria Park we design to suit the space you have, matching brick and detailing to the original house. Every extension is built to current building regulations for structure, insulation, drainage and ventilation, and we sequence the trades so the shell, roof, glazing and internal finishes follow on without gaps or delays.
Whether your extension is permitted development or needs a full planning application depends entirely on the property. A single-storey rear extension on a Bow terrace may fall under permitted development rights, while flats, conservation areas and anything larger usually need permission from Tower Hamlets Council. Leasehold apartments in Wapping and Canary Wharf conversions almost always require freeholder consent as well, since structural change to a flat is tightly limited.
We assess your title, your postcode and the council's rules before committing to a route, and we are honest when planning permission is the sensible path. Alongside planning we manage party wall notices where the extension affects a shared boundary, and we deal with building control separately for the structural and regulation sign-off. One team keeps planning, party wall and building regs moving together.
Tower Hamlets homeowners choose GS Renovation because we manage the whole extension, the foundations, steel, roof, glazing and fit-out, under one roof. We are straight about whether you need planning permission or permitted development, we handle party wall and building control, and we bring 30+ years of building across E1, E2, E3 and E14 to every project.
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!

A modest single-storey rear extension on a Bethnal Green house may be permitted development, but conservation areas, flats and larger or double-storey builds usually need a planning application to Tower Hamlets Council.
