Single and double storey extensions in Camden Town. Trusted, professional, 30+ years' hands-on experience.
GS Renovation designs and builds extensions on the Victorian and Edwardian terraces of Camden Town, from rear and side-return additions to full wrap-arounds and double-storey builds. Drawing on 30+ years across NW1, we handle foundations, steelwork, roofing and the full fit-out, so your extended home works as one considered space rather than a bolted-on box.

The classic Camden Town extension fills the narrow side return beside the rear closet wing, widening a cramped galley kitchen into an open-plan kitchen-diner that runs the full width of the house. We dig and pour new foundations to suit the ground, tie the new structure into the existing solid brick and install steel beams where we remove the outside wall, giving you a bright, level space that flows to the garden.
On wider plots nearer Regent's Park we build larger rear or wrap-around extensions, and where the roof allows we take the work up to a second storey. Throughout, we work around the reality of an occupied terrace in a busy NW1 street, sequencing deliveries, groundworks and roofing so your household keeps running while the shell goes up.
Some Camden Town extensions fall under permitted development, but many do not, so it depends on your specific property. Homes in a conservation area, flats, and anything already extended often need a full planning application to Camden Council, and a rear addition beyond the permitted size will too. We assess your house honestly, tell you which route applies and prepare the drawings and building regulations details either way.
Extending a terrace almost always touches a shared boundary, so the Party Wall Act comes into it. Excavating near the neighbour's wall or building off the party wall means serving notice on adjoining owners in good time. We coordinate this alongside the planning and building control side, so approvals, notices and the construction programme line up rather than tripping over each other.
Homeowners in Camden Town choose GS Renovation because one team carries the extension from foundations to final coat. We advise clearly on permitted development versus a planning application to Camden Council, handle party wall notices, and manage the structure, roof and fit-out together. Three decades on NW1 terraces 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!

Yes. A large share of Camden Town's homes are Victorian and Edwardian terraced properties, and we renovate them regularly. We plan each house extensions around their particular characteristics, such as solid brick walls, rear closet wings, side returns and original period features, so the result suits the building and meets building control.
It depends on the property. A modest rear or side-return extension may be permitted development, but if you are in a conservation area, in a flat, or extending beyond the permitted limits, you will need planning permission from Camden Council. Either way the build itself must meet building regulations. We check your specific house and handle whichever approvals apply.
