Mid Wales
Kitchen-diner rear extensions in Mid Wales
An open-plan kitchen, dining and family room that opens straight onto the garden. 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.
A kitchen-diner is often the reason people in Newtown extend: the back kitchen in older terraces and post-war semis is rarely big enough for a table. 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 kitchen-diner rear extension cost in Mid Wales?
For Mid Wales we work from the Wales rate: £1,770–£2,880 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) | £21,000–£34,500 |
| 4 m wide × 5 m deep (20 m²) | £35,500–£57,500 |
| 4 m wide × 6 m deep (24 m²) | £42,500–£69,000 |
Ground conditions, glazing, the roof and how far the house is opened up move the final figure within the range.
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
Should the sink face the garden?
If the plan allows, an island sink or hob facing the glass is a common choice. It needs a floor-level drain run, which is easy to lay in a new slab.
Can I have underfloor heating?
Yes. Wet underfloor heating in the new screed is the usual choice, often with the old room's radiators kept or replaced.
Where does the cooker extraction go?
Through the new wall or roof, ducted to outside. Recirculating hoods are possible but less effective.
Do you cover all of Mid Wales?
We cover 4 towns and districts in Mid Wales, including Newtown, Brecon and Welshpool.
