Wraparound extension in Southampton

Thinking about a wraparound extension in Southampton? An L-shaped extension that fills the side return and runs across the back. Our team handles the drawings, the planning route and the build, and your contract is with one company throughout.

Southampton and its postcode districts SO14, SO15, SO16 and SO17 are part of our Hampshire coverage. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in Hampshire where a side return alone would leave the room too narrow.

Do you need planning permission for a wraparound extension in Southampton?

Here is how the rules in England apply to a wraparound extension in Southampton.

In England the side part of a side return or wraparound must meet the side-extension rules (one storey, under 4 metres high, no more than half the width of the original house), and those rights do not apply on designated land. Because a wraparound combines a side and a rear extension, many need householder planning permission.

Because rear extensions often sit on or near the boundary, the Party Wall etc. Act 1996 usually applies in England. Notices go out one or two months before work depending on the type of work, and a surveyor's award is only needed if a neighbour does not consent.

Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.

What are homes in Southampton like to extend?

Around Southampton the housing ranges from inter-war semis to 1960s and 1970s estates with good-sized gardens. Many of the newer estates had permitted development rights removed by condition, so we check the planning history before anything is drawn.

FAQ

Wraparound extension questions in Southampton

Who will build my extension?

Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.

Do I need a party wall agreement?

In England, usually yes if the extension is on or near a shared boundary or the foundations are close to a neighbour's building. We serve the notices.

What roof suits a wraparound?

A flat roof with a lantern, a standing-seam pitched roof or a glazed roof over the side leg. The choice usually follows the first-floor windows above.

How long does a rear extension take to build in Southampton?

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.

What postcode areas do you cover around Southampton?

Including SO14, SO15, SO16, SO17, SO18 and SO19, and the surrounding Hampshire area.

Can I live at home while the extension is built?

Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
