Single and double storey extensions in Dalston. Trusted, professional, 30+ years' hands-on experience.
GS Renovation designs and builds extensions across Dalston, adding space to the Victorian and Edwardian terraces of E8 without losing their character. Drawing on more than 30 years in Hackney, we handle the groundworks, the steelwork and the fit-out, and guide you through whether your project is permitted development or needs a full application to Hackney Council.

The classic Dalston extension fills in the side return, the narrow strip beside the rear closet wing, to widen a cramped kitchen into a proper kitchen-diner. A wrap-around adds the rear as well, pushing out into the garden. Both need new foundations sensitive to the neighbouring terrace, steel beams over the openings, and a roof that ties cleanly into the original bay-fronted house.
Whether your project falls under permitted development or needs planning permission depends on the property, its size and any past extensions, and conservation controls vary across E8. We assess this honestly before you commit. Because the new walls sit hard against your neighbours, party wall notices are almost always required, and we serve them early so the excavation and build run to schedule.
Where the plot and the neighbours allow, a double-storey extension adds a bedroom or bathroom above the new ground-floor space, and many Dalston terraces also suit a loft conversion into the roof. These bigger projects change the roofline and are more likely to need a full planning application to Hackney Council rather than qualifying as permitted development, so early advice saves time and money.
Every extension here goes through building control for its foundations, structure, insulation, drainage and fire safety, which is separate from planning. We manage both tracks together, then complete the full fit-out, the kitchen, bathroom, electrics, plumbing, plastering and decoration, so you deal with one team from the first trench to the finished, decorated room.
Dalston homeowners choose GS Renovation because we build the whole extension, from foundations to final coat, as one accountable project. We are honest about whether you need planning permission or can build under permitted development, we handle the party wall notices your terrace requires, and we manage Hackney building control throughout. 30+ years in E8 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!
