GS Renovation designs and builds extensions across Croydon, from the wide 1930s semis in Coulsdon and Purley to the interwar family houses near Lloyd Park and Addiscombe. With 30+ years in CR0, CR2, CR7, SE25 and SE19, we handle the groundworks, the steels, the roof and the full fit-out as one project.
Rear and side-return extensions in Croydon
The generous plots typical of Croydon's interwar housing lend themselves to substantial extensions. A single-storey rear extension opens the kitchen onto the garden, while a side-return or wrap-around fills the gap alongside a 1930s semi to create a broad open-plan kitchen-diner. We dig and lay the foundations, build the walls, install the steel beams over the openings and tie the new roof into the existing house.
Whether your project is permitted development or needs a full planning application depends on the property, its size and whether it has been extended before. Many Croydon rear extensions fall under permitted development, but larger, two-storey or front schemes, and anything near a conservation area, usually need permission from Croydon Council. We assess yours honestly and handle the application where one is required.
Double-storey extensions on Croydon plots
The deeper gardens found across Purley, Coulsdon and the roads around Lloyd Park often suit a double-storey extension that adds a larger kitchen below and an extra bedroom or en-suite above. These schemes almost always need planning permission from Croydon Council, plus full building regulations approval for the foundations, the steel frame and the roof structure, which we manage from drawings through to completion.
Where the extension meets the boundary with a neighbour, or where new foundations sit within three or six metres of their wall, the Party Wall etc. Act applies and notices must be served. This is common on the tighter interwar plots in CR7 and SE25. We coordinate the planning, the party wall matters, the groundworks and the internal fit-out so the whole build stays under one accountable team.
