Wraparound extensions in Devon
An L-shaped extension that fills the side return and runs across the back. Rear extensions in Devon: we cover 21 towns including Plymouth, Exeter and Paignton, with design, approvals and the build under one contract.
In Plymouth we usually draw the wraparound and a simpler rear-only option side by side, so the planning risk and cost difference are clear. Stone-built and rendered houses are common around Devon, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.
How much does a wraparound extension cost in Devon?
Guide prices for a wraparound extension in Devon start from our South West England rate of £2,290–£3,740 per square metre, including VAT. South West prices run slightly above our West Midlands baseline; natural stone to match the house is the main variable.
| Size | Guide price inc VAT |
|---|---|
| L-shaped, about 22 m² of new floor | £50,500–£82,500 |
| L-shaped, about 30 m² of new floor | £68,500–£112,500 |
We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
Do you need planning permission in Devon?
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.

FAQ
Questions people ask
Does a wraparound need planning permission?
Often yes, because the side and rear parts are judged together. Some fit within permitted development; we check before drawing.
How long does a wraparound take?
Usually 14 to 20 weeks on site, longer than a plain rear extension because of the steelwork.
Can the corner be all glass?
Yes, with a steel or aluminium post or a structural glass corner. It needs careful thermal detailing to meet Building Regulations.
Do you cover all of Devon?
We cover 21 towns and districts in Devon, including Plymouth, Exeter and Paignton.
