Do you need planning permission for a kitchen-diner rear extension in Neath?
Here is how the rules in Wales apply to a kitchen-diner rear extension in Neath.
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 Neath like to extend?
Neath 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 Neath
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
Do you handle building control in Neath?
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.
How long does a rear extension take to build in Neath?
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 Neath?
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 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.
