GS Renovation designs and builds extensions across Bromley, adding space to the 1930s semi-detached and interwar houses that fill BR1, BR2 and BR3. With over 30 years in the borough, we handle everything from foundations and steel to the final fit-out, and we make the generous suburban plots common around Beckenham and Orpington work harder.
Rear and side-return extensions in Bromley
The generous plots on Bromley's interwar estates suit rear and wrap-around extensions particularly well, giving the room to add a large kitchen-diner without crowding the garden. On a 1930s semi we often combine a rear extension with the original side passage to create an open family space, installing a steel beam where the back wall is removed and tying the new foundations into the existing ones.
Many single storey rear extensions in BR5 and BR6 fall under permitted development, which means no full planning application, though this depends on the size, the plot and whether the house has been extended before. Larger or double storey schemes, or anything near a boundary, may need planning permission from Bromley Council. We assess your specific property and tell you honestly which route applies before you commit.
Double storey space on Bromley plots
Where a family needs another bedroom and a bigger kitchen, a double storey side or rear extension makes the most of a wide interwar plot in Chislehurst or Beckenham. We match the new brickwork, roof pitch and detailing to the 1930s original so the addition reads as part of the house rather than a bolt-on, and we design the steelwork to carry both new floors safely.
These projects usually need a full planning application to Bromley Council, and often a party wall notice where the extension meets the shared boundary with a neighbouring semi. We manage foundations, groundworks, drainage diversions, the roof and the full internal fit-out, so you deal with one team from the first trench to the final coat of paint rather than juggling separate trades.

The GS Renovation Difference in Bromley
Bromley families choose GS Renovation because we run the whole extension as one project, from the planning or permitted development check through foundations, steel, roof and fit-out. We understand the borough's interwar stock and its generous plots, coordinate any party wall matters, and keep an occupied home liveable. Backed by 30+ years across BR1 to BR7 and SE20.
