GS Renovation designs and builds extensions across Sutton, working with the generous plots that came with its 1930s semi-detached and interwar suburban houses. With over 30 years in SM1, SM2, SM3, SM5 and SM6, we handle single and double storey, rear, side-return and wrap-around projects from foundations to final fit-out.
Rear and side extensions on Sutton plots
The deep rear gardens and side access common to Sutton's interwar semis make them well suited to extending. A single storey rear extension opens the back of the house into a large kitchen-diner, while a side infill along the passage between two semis reclaims dead ground for a utility or wider kitchen. A wrap-around combines both, and a double storey adds a bedroom and en-suite above the new ground floor.
Every extension starts underground, and around Carshalton and Wallington we design foundations to suit the local ground and any nearby trees, which matters on plots close to Nonsuch Park or Beddington Park where mature planting is common. Steel beams tie the new opening back to the existing house, the roof is built to match, and we complete the fit-out including plastering, electrics, heating and decoration.
Planning and party walls in Sutton
Depending on the size and position, your extension may fall under permitted development or it may need a full planning application to Sutton Council. Larger rear extensions, anything to the front, two storey additions and homes in conservation areas or with existing restrictions usually need planning permission, while modest single storey projects often do not. We assess your specific house early and tell you honestly which route applies before you commit.
Whichever planning route applies, the build itself must satisfy building regulations, and where the extension runs up to or along the boundary with a neighbouring semi the Party Wall Act comes into play. We arrange the party wall notices, coordinate the building control inspections through foundations, steel and roof, and keep the site tidy and secure so you can carry on living in the house while the work goes ahead.

The GS Renovation Difference in Sutton
Sutton homeowners choose GS Renovation because we run the whole extension as one accountable project, from advising on permitted development versus a planning application to the groundworks, steel, roof and full fit-out. Over 30 years across the borough means we understand these interwar plots, their foundations and their party walls, and we deliver space that suits how the house actually works.
