Wraparound extensions in the West Midlands
An L-shaped extension that fills the side return and runs across the back. Across the West Midlands we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Birmingham, Coventry and Wolverhampton.
Wraparounds are the natural next step for the end-of-terrace and Victorian houses in the West Midlands where a side return alone would leave the room too narrow. Red-brick terraces and 1930s semis make up much of the West Midlands. Many already have a small kitchen lean-to at the back, which a new rear extension usually replaces rather than adds to.
How much does a wraparound extension cost in the West Midlands?
In the West Midlands, our guide for a wraparound extension is £2,200–£3,600 per square metre including VAT for a standard specification. The West Midlands is the baseline for our guide prices.
| Size | Guide price inc VAT |
|---|---|
| L-shaped, about 22 m² of new floor | £48,500–£79,000 |
| L-shaped, about 30 m² of new floor | £66,000–£108,000 |
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 in the West Midlands?
Side return infills and the side leg of a wraparound are treated as side extensions in England: single-storey, no more than 4 metres high and no wider than half the original house. They are not permitted development in conservation areas, National Parks or National Landscapes, and a joined wraparound often needs a planning application because the side and rear rules apply together.
The Party Wall etc. Act 1996 applies in England: you serve notice two months before work to a shared wall, and one month before digging foundations within 3 metres (or 6 metres for deeper foundations) of a neighbour's building. Neighbours can agree in writing; if they dissent, surveyors agree an award.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent.

FAQ
Questions people ask
Does a wraparound need planning permission?
Often yes, because the side and rear parts are judged together. Some fit within permitted development; we check before drawing.
How long does a wraparound take?
Usually 14 to 20 weeks on site, longer than a plain rear extension because of the steelwork.
Can the corner be all glass?
Yes, with a steel or aluminium post or a structural glass corner. It needs careful thermal detailing to meet Building Regulations.
Do you cover all of the West Midlands?
We cover 33 towns and districts in the West Midlands, including Birmingham, Coventry and Wolverhampton.
Who builds the extension?
Vetted building teams working under contract to us; your contract is with S&K Property Investments and Improvement Ltd.
