Single-storey rear extension in Ebbw Vale
Ground-floor space across the back of the house, usually for a kitchen, dining or family room. We design, get the approvals for and build single-storey rear extensions in Ebbw Vale and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Ebbw Vale (NP23) as part of our South Wales Valleys work. On stone terraces and post-war semis like those around Ebbw Vale, a single-storey rear extension is usually the simplest way to fix a small back kitchen without touching the bedrooms.

Do you need planning permission for a single-storey rear extension in Ebbw Vale?
Here is how the rules in Wales apply to a single-storey rear extension in Ebbw Vale.
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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Ebbw Vale like to extend?
Stone terraces along the valley floors and post-war semis higher up are typical of Ebbw Vale. Sloping sites are common, so floor levels and retaining walls are designed at the start.

FAQ
Single-storey rear extension questions in Ebbw Vale
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.
Can you match the brick or stone on my Ebbw Vale house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Is a flat roof or a pitched roof better?
A warm flat roof keeps the extension low under first-floor windows and suits a roof lantern; a pitched or lean-to roof gives a vaulted ceiling. Both last for decades when built properly.
How long does a rear extension take to build in Ebbw Vale?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Do I need planning permission for a rear extension in Ebbw Vale?
Often not for a single-storey rear extension of up to 4 metres under Welsh permitted development. Wales has no prior approval route for deeper extensions.
Do you handle building control in Ebbw Vale?
Yes. We apply to the council or a registered approver under the Welsh regulations and hand over the completion certificate.
