Wraparound extension in Plymouth
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 Plymouth and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Plymouth (PL2, PL3, PL4 and PL5) as part of our Devon work. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in Devon where a side return alone would leave the room too narrow.

How much does a wraparound extension cost in Plymouth?
For Plymouth we work from the South West England rate: £2,290–£3,740 per square metre of new floor, including VAT, standard specification. 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 for a wraparound extension in Plymouth?
The planning route for a wraparound extension in Plymouth 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 Plymouth like to extend?
Stone-built and rendered houses are common around Plymouth, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.
