Do you need planning permission for a kitchen-diner rear extension in Clydach?
Whether your kitchen-diner rear extension in Clydach 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. 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 Clydach like to extend?
Clydach has Victorian terraces near the centre and semis further out. Welsh permitted development allows up to 4 metres at the rear for many houses.

FAQ
Kitchen-diner rear extension questions in Clydach
Do I need planning permission for a rear extension in Clydach?
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 Clydach?
Yes. We apply to the council or a registered approver under the Welsh regulations and hand over the completion certificate.
Can I add a utility room?
Often. A narrow utility or boot room along one side keeps the washing machine out of the open-plan space.
What postcode areas do you cover around Clydach?
Including SA5, SA6 and SA7, and the surrounding Swansea Bay area.
Can you match the brick or stone on my Clydach house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
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.
