Wraparound extension in Bethnal Green
For homes in Bethnal Green, 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 Bethnal Green (E1, E2 and E8) as part of our Greater London work. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in Greater London where a side return alone would leave the room too narrow.

How much does a wraparound extension cost in Bethnal Green?
For Bethnal Green we work from the London rate: £2,860–£4,680 per square metre of new floor, including VAT, standard specification. London prices sit at the top of our range because of labour rates, access through the house, parking suspensions and skip licences.
| Size | Guide price inc VAT |
|---|---|
| L-shaped, about 22 m² of new floor | £63,000–£103,000 |
| L-shaped, about 30 m² of new floor | £86,000–£140,500 |
These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission for a wraparound extension in Bethnal Green?
Whether your wraparound extension in Bethnal Green needs a planning application depends on its size, your house and any local restrictions.
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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Bethnal Green like to extend?
Much of Bethnal Green is Victorian and Edwardian terraced housing with narrow back additions, which suits side returns, wraparounds and 3 metre rear extensions. Many streets are in conservation areas, gardens are short, and almost everything comes through the house or along a rear alley.

FAQ
Wraparound extension questions in Bethnal Green
Do you handle building control in Bethnal Green?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
How long does a rear extension take to build in Bethnal Green?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
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 a party wall agreement?
In England, usually yes if the extension is on or near a shared boundary or the foundations are close to a neighbour's building. We serve the notices.
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.
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
