GS Renovation designs and builds extensions throughout Edgware and HA8, making the most of the generous plots that came with its 1930s and interwar houses. With over 30 years of experience across Barnet, we handle everything from single-storey rear additions to double-storey and wrap-around builds on these suburban semis and detached homes.
Rear and side extensions in Edgware
Edgware's interwar semis and detached houses were built on generous plots, which gives real scope for extending. A single-storey rear extension opens the back of the house into a large kitchen-diner, while a side return or side infill uses the space alongside the house that many 1930s plots enjoy. A wrap-around combines both, and a double-storey extension can add a bedroom and en-suite above the new ground-floor room.
We start with the groundworks, digging and pouring foundations suited to the local ground and any nearby trees, then build the walls, install the steel beams that carry the openings, and complete the roof. Throughout, we manage the full fit-out, including plastering, electrics, plumbing, flooring and decoration, so your Edgware extension is finished properly rather than left as a shell for other trades.
Planning and permitted development in HA8
Whether your Edgware extension needs a full planning application or falls under permitted development depends on the property. Many single-storey rear extensions on interwar semis can proceed under permitted development rights, subject to size, height and boundary limits. Larger builds, double-storey additions, or work on a property in a conservation area or with restricted rights usually require a full planning application to Barnet Council.
We assess your specific house and plot before committing to a route, and we prepare and submit the application to Barnet Council where one is needed. The structural work is covered separately by building regulations, with building control inspecting the foundations, steel and drainage. Where an extension sits near or on the shared party wall of a semi, we also handle the party wall notices to your neighbour.
