Wraparound extension in Maidenhead
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 Maidenhead and the surrounding area, with one contract from the first survey to building control sign-off.
Maidenhead and its postcode districts SL6 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 Maidenhead?
The planning route for a wraparound extension in Maidenhead is set by England's householder rules and your council.
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 Maidenhead like to extend?
Around Maidenhead 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. In Maidenhead we usually draw the wraparound and a simpler rear-only option side by side, so the planning risk and cost difference are clear.
