Do you need planning permission for a kitchen-diner rear extension in Aberdare?
Planning for a kitchen-diner rear extension in Aberdare follows the Welsh householder rules.
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 Aberdare like to extend?
Aberdare is largely terraced streets on sloping ground, where back gardens step up or down from the house. Excavation, retaining walls and drainage are priced at the survey.

FAQ
Kitchen-diner rear extension questions in Aberdare
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.
How long does a rear extension take to build in Aberdare?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.

Through the new wall or roof, ducted to outside. Recirculating hoods are possible but less effective.
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
Can you match the brick or stone on my Aberdare house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
