Single and double storey extensions in Hackney. Trusted, professional, 30+ years' hands-on experience.
GS Renovation designs and builds extensions across Hackney, working with both the borough's warehouse conversions and its period terraces near Broadway Market and London Fields. With more than 30 years in E2, E8, E9 and N16, we handle foundations, steelwork, roofing and fit-out, and guide you through Hackney Council's planning rules from the first drawing.

The classic Hackney extension adds space to a Victorian terrace, either extending the rear or filling the side return to widen a narrow kitchen. We dig and lay the foundations, allowing for any trees or shallow drains common on these older plots, then form the walls and fit steel beams where the back of the house opens up. A well-detailed flat or pitched roof, with rooflights, keeps the new space bright and usable.
Whether your project is permitted development or needs a full planning application depends on the property. Many single-storey rear extensions in Hackney fall under permitted development, but flats, homes in conservation areas and larger double-storey schemes usually need permission from Hackney Council. We assess your specific address, prepare the application where required, and handle any party wall notices with neighbours before building work begins on your E8 or N16 home.
Extending a warehouse conversion or new-build apartment is a different matter from extending a house. Structural change is limited, and any alteration to the building's fabric usually needs the freeholder's consent and coordination with the managing agent. Rather than a rear extension, projects here often mean reconfiguring the existing envelope, adding a mezzanine where the ceiling height allows, or enclosing a balcony, all within the building-management rules set out in your lease.
Where a genuine extension is possible, such as on the ground floor of a converted building with garden rights, we work through both Hackney Council's planning requirements and the terms of your lease. We prepare the structural and drainage details, manage sound insulation between units, and sequence the work to minimise disruption to neighbours in your block across Dalston, Hoxton or Shoreditch while keeping the managing agent informed throughout.
Homeowners across Hackney choose GS Renovation because we understand both sides of the borough, the freehold terraces and the leasehold conversions. We tell you honestly whether your extension is permitted development or a planning matter, coordinate party walls and any licence to alter, and deliver the groundwork, steel and finish as one project backed by 30+ years.
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 on Hackney houses are permitted development, but flats and conversions have no such rights, and homes in the borough's conservation areas usually need consent. We check your exact address and the council's records, then either confirm permitted development or prepare and submit the planning application to Hackney Council for you.
