Do you need planning permission for a single-storey rear extension in Aberkenfig?
Whether your single-storey rear extension in Aberkenfig needs a planning application depends on its size, your house and any local restrictions.
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. 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 Aberkenfig like to extend?
Stone terraces along the valley floors and post-war semis higher up are typical of Aberkenfig. Sloping sites are common, so floor levels and retaining walls are designed at the start.

FAQ
Single-storey rear extension questions in Aberkenfig
Do you handle building control in Aberkenfig?
Yes. We apply to the council or a registered approver under the Welsh regulations and hand over the completion certificate.
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 a structural engineer?
Yes for the beam over the new opening and usually for the foundations. Their calculations go to building control with the drawings.
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.
Is the site visit in Aberkenfig free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Do I need planning permission for a rear extension in Aberkenfig?
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.
