How much does a bungalow rear extension cost in Newport?
In Newport, our guide for a bungalow rear extension is £1,720–£2,790 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 |
|---|---|
| 3 m wide × 4 m deep (12 m²) | £20,500–£33,500 |
| 4 m wide × 6 m deep (24 m²) | £41,500–£67,000 |
These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission for a bungalow rear extension in Newport?
The planning route for a bungalow rear extension in Newport is set by Wales's householder rules and your council.
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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Newport like to extend?
Older terraces near the centre and post-war semis further out are typical of Newport. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.

FAQ
Bungalow rear extension questions in Newport
How much does a bungalow rear extension cost in Newport?
As a guide, £1,720–£2,790 per square metre including VAT for a standard specification. For example, 3 m wide × 4 m deep (12 m²): about £20,500–£33,500 at that rate. Your written price follows the survey.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Do I need to move out?
Rarely; the opening into the bungalow is made late in the build.
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
Do I need a party wall agreement?
In Wales, usually yes if the extension is on or near a shared boundary or close to a neighbour's foundations. We serve the notices.
Can you match the brick or stone on my Newport house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
