Crouch End, Greater London
Wraparound extension in Crouch End
An L-shaped extension that fills the side return and runs across the back. We design, get the approvals for and build wraparound extensions in Crouch End and the surrounding area, with one contract from the first survey to building control sign-off.
Crouch End is covered from our Greater London round, including N6, N8 and N19. 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 Crouch End?
For Crouch End 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 |
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 Crouch End?
The planning route for a wraparound extension in Crouch End is set by England's householder rules and your council.
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 Crouch End like to extend?
Much of Crouch End 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.
