Do you need planning permission for a bungalow rear extension in Abergavenny?
The planning route for a bungalow rear extension in Abergavenny 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 Abergavenny like to extend?
Older terraces near the centre and post-war semis further out are typical of Abergavenny. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.

FAQ
Bungalow rear extension questions in Abergavenny
Is the site visit in Abergavenny free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
How long does a rear extension take to build in Abergavenny?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
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 you match the brick or stone on my Abergavenny house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
