Wraparound extension in Ashtead
For homes in Ashtead, 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 Ashtead (KT18, KT21 and KT22) as part of our Surrey work. Wraparound projects around Ashtead often involve two neighbours, so we start the party wall conversations early.

Do you need planning permission for a wraparound extension in Ashtead?
Planning for a wraparound extension in Ashtead follows the English householder rules.
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 Ashtead like to extend?
Commuter semis and detached houses make up much of Ashtead, and longer gardens make England's prior approval route for deeper rear extensions worth considering.

FAQ
Wraparound extension questions in Ashtead
How much does a wraparound extension cost in Ashtead?
As a guide, £2,460–£4,030 per square metre including VAT for a standard specification. For example, L-shaped, about 22 m² of new floor: about £54,000–£88,500 at that rate. Your written price follows the survey.
Is the site visit in Ashtead free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
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.
Do I need planning permission for a rear extension in Ashtead?
Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.
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 long does a rear extension take to build in Ashtead?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
