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

FAQ
Kitchen-diner rear extension questions in Aberystwyth
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.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
Should the sink face the garden?
If the plan allows, an island sink or hob facing the glass is a common choice. It needs a floor-level drain run, which is easy to lay in a new slab.
How long does a rear extension take to build in Aberystwyth?
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 you handle building control in Aberystwyth?
Yes. We apply to the council or a registered approver under the Welsh regulations and hand over the completion certificate.
Can you match the brick or stone on my Aberystwyth house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
