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 and manage the structure, roof and fit-out together. Three decades on NW1 terraces means fewer surprises and a build that lasts.

FAQ
Everything needed to finish the work and get it signed off. The house extensions quotation for a Camden Town home covers labour, materials, the structural engineer where the design requires one, the Camden Council building control element, and the making good afterwards. Anything genuinely uncertain at the NW1 property is flagged before we start rather than added later. GS Renovation issues it after a free NW1 survey, with no obligation in Camden Town or the wider Camden. As a rough guide, house extensions in London typically starts from roughly £40,000 for a single-storey rear extension and rises with size and specification (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
Longer than the fastest quote you will be given, and shorter than an open-ended one. GS Renovation would rather set house extensions dates a Camden Town homeowner can plan around than win the NW1 job on a programme nobody can meet. The stages, the trades and the Camden Council points are all written down. You are updated against them weekly throughout the Camden project. Ring 07472 424 226 and we will describe how a comparable NW1 project ran.
References, reviews and finished addresses are all available on request. GS Renovation has carried out house extensions across Camden Town and Camden, and the NW1 area in particular, so there is usually something nearby to look at. Email info@gsrenovationltd.co.uk and we will send details. Checking a contractor properly before committing is time well spent, in North London as anywhere else. Ring 07472 424 226 and we will point you at recently finished NW1 work in Camden Town.
Always, regardless of the planning route. Foundations, structure, insulation, drainage and ventilation are all inspected. GS Renovation submits the application to Camden Council and books the inspections through to the completion certificate on your Camden Town project.
It is, and pretending otherwise is how fixed prices become variable ones. Two and three-bedroom Victorian terraces, a good many now split into flats rarely offer regular dimensions, so house extensions take longer in the finishing at an NW1 address and needs more investigation beforehand. GS Renovation allows for that in the quotation for your Camden Town home. Camden Council will expect the method to suit the original construction. GS Renovation will describe how house extensions are normally sequenced in an NW1 property before any work starts.
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.
No minimum. GS Renovation takes small house extensions work at an NW1 property as readily as a full project, and a modest job is how many of our larger Camden Town contracts began. The survey is free either way. Ring 07472 424 226 and describe what you have in mind for your Camden home. We will say honestly if another trade suits you better. The NW1 survey is free whether the Camden job is large or small.
