Rear extensions for bungalows in Mid Wales
Single-storey rear extensions that keep everything on one level. 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.
For Newtown bungalows we design the roof first, because the low eaves decide the height of the new room. Older terraces near the centre and post-war semis further out are typical of Mid Wales. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.
How much does a bungalow rear extension cost in Mid Wales?
For Mid Wales we work from the Wales rate: £1,720–£2,790 per square metre of new floor, including VAT, standard specification. Prices in Wales sit below our West Midlands baseline; sloping sites are the main variable.
| Size | Guide price inc VAT |
|---|---|
| 3 m wide × 4 m deep (12 m²) | £20,500–£33,500 |
| 4 m wide × 6 m deep (24 m²) | £41,500–£67,000 |
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?
The Welsh Government's householder rules let many homes add a single-storey rear extension up to 4 metres deep and 4 metres high without a planning application. Deeper projects go through a householder application, because Wales has no prior approval route.
Conservation areas, National Parks and National Landscapes restrict permitted development in Wales, and listed buildings need listed building consent.

FAQ
Questions people ask
Can a bungalow extension be fully accessible?
Yes: level thresholds, wider doors and a wet room are straightforward to design in.
Will the roof look odd?
Not if the pitch and tiles match. Where the eaves are low, a flat-roofed section with a lantern is an alternative.
Can I extend the loft as well?
Sometimes, but that is a different project; a rear extension keeps everything on one level.
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?
Vetted building teams working under contract to us; your contract is with S&K Property Investments and Improvement Ltd.
