GS Renovation designs and builds extensions on the Victorian and Edwardian terraces of Harlesden, from rear and side-return additions to full wrap-arounds and double storeys. With over 30 years of building in NW10 and across Brent, we handle the groundworks, steelwork, roof and fit-out as one accountable project.
Side-return and rear extensions in Harlesden
The bay-fronted terraces around Harlesden almost always have a side return, that narrow strip of yard alongside the original rear closet wing. Filling it in is the classic NW10 project, widening a cramped galley kitchen into a bright open-plan kitchen-diner. We dig and pour the new foundations, build the flank wall, and install steel beams to carry the existing structure where the old external wall comes out.
A rear extension pushes the ground floor further into the garden, and a wrap-around combines both moves for a generous L-shaped living space. We match brickwork and detailing to the Victorian and Edwardian character where it shows, add rooflights or a lantern for daylight, and manage the drainage runs and party wall matters that come with building tight against the neighbours on either side.
Planning and permitted development in Brent
Whether your Harlesden extension is permitted development or needs a full planning application depends on the property and the size of the build. Many single-storey rear extensions on these NW10 terraces fall within permitted development, but double storeys, larger footprints, and any home in a conservation area or that has already been extended usually need permission from Brent Council. We assess this at the outset so there are no surprises.
Whichever route applies, the structural side is controlled under building regulations, so foundations, beams and the roof are all inspected and signed off by building control. Because these terraces share party walls, we also handle the Party Wall Act notices for the excavation and any work against the boundary. One team ties the planning position, the structure and the finished rooms together.
