GS Renovation designs and builds extensions across Brent, working with the borough's mansion blocks, interwar semis and Victorian terraces in NW2, NW9, NW10 and HA0. With 30+ years of local experience, we take a rear, side-return or wrap-around extension from foundations and steelwork through to a fully fitted finish.
Rear and side-return extensions in Brent
The interwar semis and Victorian terraces around Wembley, Willesden and Harlesden lend themselves well to extending. A side-return infill captures the wasted alley beside the kitchen, while a single or double storey rear extension pushes into the garden to create an open-plan kitchen-diner. We dig and pour the foundations, install the steel beams that carry the opening, build up the walls and tie the new roof into the existing one.
Ground conditions vary across Brent, and nearby trees or made-up ground can mean deeper or wider foundations, which our engineer specifies. Where your semi shares a boundary or party wall with the neighbour, the Party Wall Act usually applies and we help you serve notice early. We then handle the full fit-out, so the new space is ready to use rather than a shell.
Planning and permitted development in Brent
Whether your Brent extension is permitted development or needs a full planning application to Brent Council depends on the property. Many houses in NW10 and HA9 can extend under permitted development rights within the size and height limits, but flats have no such rights, and homes on designated land or in a conservation area usually need a formal application. We assess your specific address before you commit.
If a planning application is the right route, we prepare the drawings and manage the submission to Brent Council on your behalf, then move to building regulations for the structure, insulation, drainage and fire safety. Every extension needs building control inspection regardless of the planning position, and we book and attend those inspections so the work is certified and signed off properly at completion.
