Wraparound extensions in Berkshire
An L-shaped extension that fills the side return and runs across the back. Rear extensions in Berkshire: we cover 14 towns including Reading, Slough and Bracknell, with design, approvals and the build under one contract.
Wraparounds are the natural next step for the end-of-terrace and Victorian houses in Berkshire where a side return alone would leave the room too narrow. Around Berkshire the housing ranges from inter-war semis to 1960s and 1970s estates with good-sized gardens. Many of the newer estates had permitted development rights removed by condition, so we check the planning history before anything is drawn.
How much does a wraparound extension cost in Berkshire?
For Berkshire 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 |
These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission in Berkshire?
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 Berkshire?
We cover 14 towns and districts in Berkshire, including Reading, Slough and Bracknell.
