Wraparound extension in Dunstable
For homes in Dunstable, a wraparound extension is often the simplest way to gain space without moving. An L-shaped extension that fills the side return and runs across the back. We take it from survey to completion certificate.
We cover Dunstable (LU6) as part of our Bedfordshire work. Wraparound projects around Dunstable often involve two neighbours, so we start the party wall conversations early.

How much does a wraparound extension cost in Dunstable?
A wraparound extension in Dunstable is priced at £2,330–£3,820 per square metre including VAT as a guide, before kitchen fit-out and fees. East of England prices run slightly above our West Midlands baseline; clay soils near trees are the main foundation variable.

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 Dunstable?
Here is how the rules in England apply to a wraparound extension in Dunstable.
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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Dunstable like to extend?
Post-war semis and newer estates are typical of Dunstable, and many have room for a full-width extension. Shrinkable clay is common in the East of England, so foundations near trees and hedges are designed to NHBC-style depth guidance.

FAQ
Wraparound extension questions in Dunstable
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
How much does a wraparound extension cost in Dunstable?
As a guide, £2,330–£3,820 per square metre including VAT for a standard specification. For example, L-shaped, about 22 m² of new floor: about £51,500–£84,000 at that rate. Your written price follows the survey.
Will it take a lot of garden?
Less than a deep rear extension of the same area, because part of the space comes from the side passage.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
How long does a rear extension take to build in Dunstable?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Do you handle building control in Dunstable?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
