Single and double storey extensions in Whitechapel. Trusted, professional, 30+ years' hands-on experience.
GS Renovation designs and builds house extensions throughout Whitechapel, working with the bay-fronted Victorian and Edwardian terraces that define much of E1. With 30+ years across Tower Hamlets, we handle rear, side-return and wrap-around extensions from the groundworks up, giving these period homes the extra kitchen, dining and family space that suits how people actually live near Canary Wharf and the City.

The side return, that narrow strip of dead space beside the rear closet wing, is the classic opportunity on a Whitechapel terrace. Filling it and pushing out to the rear turns a cramped galley kitchen into a wide, light open-plan kitchen-diner. We dig and pour the foundations, allowing for any nearby trees and the made-up ground common across E1, then build up in matching or complementary brick.
A rear extension almost always needs a steel beam where the old back wall comes out, sized by a structural engineer and tied into the existing structure. We manage the roof works, whether a flat roof with rooflights or a pitched addition, along with the glazing, drainage and the full internal fit-out. The aim is a space that feels part of the original house, not bolted on.
Whether your extension is permitted development or needs a full planning application depends on the property. Many single-storey rear extensions on Whitechapel terraces fall under permitted development, but corner plots, flats, larger schemes and anything in a conservation area or affecting a listed building need permission from Tower Hamlets Council. We assess your specific E1 address early and tell you honestly which route applies before you commit.
Because these terraces sit wall to wall, extensions almost always involve the Party Wall Act, whether you are building off the shared boundary, excavating near it for foundations or cutting into it for the new steel. We serve the correct notices to your neighbours and keep the build within building regulations, with building control inspecting the foundations, structure and drainage through to sign-off.
Whitechapel homeowners choose GS Renovation because we run the whole extension as one accountable project, from the first foundation to the last coat of paint. We know how E1 terraces are built, when a scheme is permitted development and when Tower Hamlets planning applies, and how to keep neighbours onside through the party wall process. 30+ years of local work stands behind every job.
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!
