GS Renovation designs and builds extensions across Bexley, making the most of the generous plots that came with the borough's 1930s and interwar semis. Homeowners in Bexleyheath, Sidcup and Welling call us to add space to family houses in DA1, DA5 and SE2. With 30+ years behind us, we handle everything from foundations to final fit-out.
Rear and side-return extensions in Bexley
The wide side access on a typical Bexley semi is ideal for a side-return or wrap-around extension, filling the gap between the house and the boundary to widen a cramped kitchen. We dig and pour the foundations, build the cavity walls to match the interwar brickwork, and install the steel beams that carry the existing rear wall once it opens into the new space. A warm flat or pitched roof closes it in.
Double-storey rear extensions suit the larger family homes around Danson Park and Hall Place, adding a bedroom and bathroom above a bigger kitchen-diner below. Foundations go deeper to carry the extra load, and we watch for the mature trees common on these older plots, which can affect the foundation design. Throughout, we protect the garden, keep the site tidy and sequence the trades so your home stays liveable while the build progresses.
Planning and party walls in Bexley
Many single-storey rear extensions on Bexley's suburban plots fall under permitted development, meaning no full planning application, though corner plots, converted properties and anything near a conservation area often need permission from Bexley Council. We advise early on which route applies, prepare the drawings, and submit a lawful development certificate or a planning application as needed. Either way, the structural work still needs building regulations approval and staged inspection.
Because the semis of DA5, DA6 and DA7 share a boundary and a party wall with the house next door, extensions frequently trigger the Party Wall Act. Digging foundations within three metres of the neighbour's wall, or building up to the boundary, means serving notice before work starts. We manage the notices, coordinate with your neighbours, and keep building control inspections booked at foundation, damp-proof and completion stages.
