Wraparound extension in Andover
We plan and build wraparound extensions for homeowners in Andover. An L-shaped extension that fills the side return and runs across the back. Start with a free site visit, then a written price once the design is agreed.
Andover sits in Hampshire, with postcode districts including SP10. In Andover we usually draw the wraparound and a simpler rear-only option side by side, so the planning risk and cost difference are clear.

How much does a wraparound extension cost in Andover?
For Andover we work from the South East England rate: £2,460–£4,030 per square metre of new floor, including VAT, standard specification. 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 |
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 Andover?
Here is how the rules in England apply to a wraparound extension in Andover.
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. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Andover like to extend?
Andover 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 a wraparound extension in Andover comes together
Survey visit
We visit free of charge, measure up, check access, drainage and neighbours' extensions, and note what you want the room to do.
Options and costs
We draw layout options and price each one, so the budget shapes the design rather than surprising you later.
Planning and regulations
We take the design through the right planning route, then produce the construction drawings and engineer's calculations for building control.
Written price, then build
Once the design and approvals are in place, you get a fixed written price and programme, and we build through to sign-off.
