Wraparound extensions in Mid Wales
An L-shaped extension that fills the side return and runs across the back. Across Mid Wales we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Newtown, Brecon and Welshpool.
In Newtown we usually draw the wraparound and a simpler rear-only option side by side, so the planning risk and cost difference are clear. Mid Wales has Victorian terraces near the centre and semis further out. Welsh permitted development allows up to 4 metres at the rear for many houses.
How much does a wraparound extension cost in Mid Wales?
In Mid Wales, our guide for a wraparound extension is £2,050–£3,350 per square metre including VAT for a standard specification. Prices in Wales sit below our West Midlands baseline; sloping sites are the main variable.
| Size | Guide price inc VAT |
|---|---|
| L-shaped, about 22 m² of new floor | £45,000–£73,500 |
| L-shaped, about 30 m² of new floor | £61,500–£100,500 |
Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.
Do you need planning permission in Mid Wales?
In Wales a single-storey side extension can be permitted development if it is no more than 4 metres high and the house ends up no more than 50% wider than the original. Many side return infills on terraced streets, and most wraparounds, go through a householder application.
The Party Wall etc. Act 1996 also applies in Wales: two months' notice for work to a shared wall and one month for foundations dug close to a neighbour's building.
Conservation areas, National Parks and National Landscapes restrict permitted development in Wales, and listed buildings 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 Mid Wales?
We cover 4 towns and districts in Mid Wales, including Newtown, Brecon and Welshpool.
Who builds the extension?
