GS Renovation designs and builds extensions across Welling, working with the 1930s semi-detached and interwar houses that give DA16 its character. Those generous plots and side accesses suit rear and side-return additions particularly well. With 30+ years in Bexley, we handle the foundations, steelwork, roof and full fit-out as one managed project.
Rear and side extensions on Welling plots
The wide, deep gardens common to Welling's interwar semis are ideal for single storey rear extensions that open the kitchen onto the garden, and the side access many of these houses retain makes a side-return or wrap-around addition genuinely practical. We start with proper foundations and groundworks sized to the ground conditions on your plot, then build up in blockwork to match the existing brickwork and rooflines of the 1930s streetscape.
Double storey extensions add a bedroom and often an en-suite above a larger kitchen below, which suits families staying put in DA16 rather than moving on. We install the steel beams that carry the new openings, tie the new structure into the original house correctly, and complete the roof works so the finished extension reads as part of the original interwar home rather than an afterthought bolted on the back.
Planning and party walls in Welling
An extension may fall under permitted development or it may need a full planning application to Bexley Council, and which route applies depends on the size, the height and whether your property sits under any restrictions. Many modest single storey rear extensions in Welling proceed under permitted development, while larger, double storey or more prominent schemes need consent. We advise honestly on the likely route before you commit and prepare the drawings either way.
Whichever planning route applies, the building work itself must meet building regulations, with foundations, steel, insulation and drainage all inspected and signed off. Because these are semi-detached houses, extensions near the shared boundary usually trigger the Party Wall Act, so you serve notice on the neighbour in good time. Getting the planning, the building control and the party wall matters aligned early keeps a Welling extension moving without avoidable delays.
