Sunninghill, Berkshire
Wraparound extension in Sunninghill
An L-shaped extension that fills the side return and runs across the back. We design, get the approvals for and build wraparound extensions in Sunninghill and the surrounding area, with one contract from the first survey to building control sign-off.
Sunninghill and its postcode districts SL5 are part of our Berkshire coverage. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in Berkshire where a side return alone would leave the room too narrow.

Do you need planning permission for a wraparound extension in Sunninghill?
Here is how the rules in England apply to a wraparound extension in Sunninghill.
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 Sunninghill like to extend?
Around Sunninghill 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 Sunninghill
Do you handle building control in Sunninghill?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
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.
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.
Is the site visit in Sunninghill free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
How long does a rear extension take to build in Sunninghill?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
