For over 30 years GS Renovation has designed and built extensions across Pinner, working with the bay-fronted Victorian and Edwardian terraces, period cottages and interwar semis that fill HA5. Whether you want a rear kitchen extension, a side-return infill or a double-storey addition, we handle groundworks, steel and fit-out, and tell you honestly whether it is permitted development or needs Harrow Council planning.
Side-return and rear extensions in Pinner
The side return beside a Pinner terrace's rear closet wing is often wasted, a narrow strip of side passage that can be pulled into the house to widen a cramped galley kitchen. We dig new foundations to suit the ground and any nearby trees, tie into the existing wall, and drop a steel beam across the old rear opening so the kitchen and the new infill read as one bright, open space.
A full-width rear extension goes further, extending across the back of the terrace to create a kitchen-diner opening onto the garden. We manage the groundworks, damp-proofing, steel, roof (whether a warm flat roof with a lantern or a pitched tiled roof) and the glazing. Because these terraces sit on shared party walls, we also handle the party wall notices to the neighbours before excavation starts, so nothing stalls once we are on site.
Planning and permitted development in Pinner
Many single-storey rear extensions in Pinner fall under permitted development, but the rights are not unlimited, and parts of the area near Pinner Village sit within a conservation area where they are tightened or removed. If your terrace or cottage is in that zone, is listed, or you want a larger or double-storey addition, you will need a full planning application to Harrow Council. We assess this at the outset so there are no surprises later.
Whichever route applies, the structural side is governed by building regulations, not planning, so foundations, beams, insulation and fire safety all need building control inspection and sign-off. We prepare the drawings, submit the applications and coordinate the engineer and building control together. On interwar semis we also watch daylight and boundary distances to neighbours, which often shape how far a side extension can reasonably go before it becomes a problem.
