Wraparound extensions in Kent
An L-shaped extension that fills the side return and runs across the back. We design and build rear extensions across Kent, from Maidstone and Gillingham to Chatham, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Wraparound projects around Maidstone often involve two neighbours, so we start the party wall conversations early. Kent has a mix of Victorian terraces near the centre and larger Edwardian and inter-war houses further out. Clay soils across much of the South East mean deeper foundations near trees, which we plan for at the survey.
How much does a wraparound extension cost in Kent?
A wraparound extension in Kent is priced at £2,460–£4,030 per square metre including VAT as a guide, before kitchen fit-out and fees. South East prices run above our West Midlands baseline, mainly on labour rates and clay-soil foundations.
| Size | Guide price inc VAT |
|---|---|
| L-shaped, about 22 m² of new floor | £54,000–£88,500 |
| L-shaped, about 30 m² of new floor | £74,000–£121,000 |
These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission in Kent?
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 Kent?
We cover 31 towns and districts in Kent, including Maidstone, Gillingham and Chatham.
