How much does a bungalow rear extension cost in Abercarn?
For Abercarn 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 for a bungalow rear extension in Abercarn?
The planning route for a bungalow rear extension in Abercarn is set by Wales's householder rules and your council.
Welsh permitted development allows a single-storey rear extension of up to 4 metres in depth and 4 metres in height, subject to boundary and garden-coverage limits. There is no larger-extension prior approval scheme in Wales.
Conservation areas, National Parks and National Landscapes restrict permitted development in Wales, and listed buildings need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development or a householder planning application.
What are homes in Abercarn like to extend?
Stone terraces along the valley floors and post-war semis higher up are typical of Abercarn. Sloping sites are common, so floor levels and retaining walls are designed at the start.
