GS Renovation designs and builds extensions across Ruislip, making the most of the generous plots that came with the area's 1930s and interwar houses. With over 30 years of building experience in HA4 and the wider Hillingdon borough, we handle everything from foundations and steel to the final fit-out under one accountable team.
Rear and side-return extensions in Ruislip
Many Ruislip semis sit on deep, wide plots, which makes them well suited to single and double storey rear extensions and to filling in the side passage between paired houses. A rear extension can turn a cramped 1930s kitchen into an open-plan kitchen-diner opening onto the garden, while a wrap-around combines the rear and the side return for a much larger ground floor. We set out the groundworks, pour the foundations and build up in brick to match the interwar character.
Where the extension removes an external wall to connect old and new, we install a steel beam sized by a structural engineer and bearing onto padstones, then take the new roof, whether flat, pitched or a lantern rooflight, up to a weathertight finish. On a paired Ruislip semi the flank or rear wall is often a party wall, so the Party Wall Act applies and you serve the notices your neighbour is entitled to receive before we break ground.
Planning and permitted development in Ruislip
Not every Ruislip extension needs a planning application. Many single storey rear extensions fall under permitted development, which lets you build within set size and height limits without full planning permission, though the exact allowance depends on your plot and whether earlier owners have already extended. Larger schemes, most double storey work, and anything affecting the front or a prominent side elevation usually need a full planning application to Hillingdon Council, and permitted development rights can be restricted on certain roads.
We assess your specific house early, tell you honestly whether it is permitted development or a planning application, and handle the route with the council either way. Whichever path applies, the structural and building work itself is governed by building regulations, so foundations, steel, drainage and insulation are all inspected by building control. From first drawings to the full internal fit-out, plastering, electrics, plumbing and decoration, one team sees the extension through.
