Wraparound extensions in Cambridgeshire
An L-shaped extension that fills the side return and runs across the back. Across Cambridgeshire we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Peterborough, Cambridge and Wisbech.
Wraparound projects around Peterborough often involve two neighbours, so we start the party wall conversations early. Cambridgeshire mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.
How much does a wraparound extension cost in Cambridgeshire?
Guide prices for a wraparound extension in Cambridgeshire start from our East of England rate of £2,330–£3,820 per square metre, including VAT. East of England prices run slightly above our West Midlands baseline; clay soils near trees are the main foundation variable.
| Size | Guide price inc VAT |
|---|---|
| L-shaped, about 22 m² of new floor | £51,500–£84,000 |
| L-shaped, about 30 m² of new floor | £70,000–£114,500 |
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 Cambridgeshire?
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 Cambridgeshire?
We cover 11 towns and districts in Cambridgeshire, including Peterborough, Cambridge and Wisbech.
