GS Renovation designs and builds house extensions across Orpington, where interwar semis and detached homes sit on the generous plots that make Bromley's suburbs so well suited to extending. Drawing on more than 30 years in BR6, we handle everything from foundations and steelwork to the final fit-out, giving families more space without leaving the neighbourhood they love.
Rear and side-return extensions in Orpington
The wide plots typical of 1930s Orpington houses lend themselves to single and double storey rear extensions, side-return infills and full wrap-around designs. We start with proper foundations and groundworks sized to the ground conditions, then form the new openings with steel beams calculated by our engineer and signed off by building control. The result blends into the original house rather than looking bolted on to the back.
Extending across the side of a detached or semi-detached Orpington home often means widening the kitchen or creating a new family room. We match brickwork and rooflines to the interwar character of the street, install the roof works, and carry out a complete fit-out including plastering, electrics, plumbing and decoration, so you move straight into a finished space rather than a shell that needs another trade to complete.
Planning and party walls for Bromley homes
Some Orpington extensions fall under permitted development, while others need a full planning application to Bromley Council. It depends on the size, height and position of the extension and whether the property sits in a conservation area or has had permitted development rights removed. We assess your specific house early, advise honestly on which route applies and prepare the drawings and submissions so there are no surprises once building starts.
On the semi-detached homes so common in BR6, extending near or against the boundary brings the Party Wall Act into play, and notices must be served on neighbours before work begins. Foundations dug close to a shared boundary can also trigger the Act. We manage these party wall matters alongside the building regulations approvals, keeping both the council and your neighbours informed so the project runs smoothly.
