Do you need planning permission for a kitchen-diner rear extension in Caerleon?
The planning route for a kitchen-diner rear extension in Caerleon is set by Wales's householder rules and your council.
In Wales a single-storey rear extension can often be permitted development if it projects no more than 4 metres beyond the rear wall and is no more than 4 metres high. Wales has no prior approval route for deeper extensions, so anything bigger needs a householder planning application.
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 Caerleon like to extend?
Older terraces near the centre and post-war semis further out are typical of Caerleon. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.

FAQ
Kitchen-diner rear extension questions in Caerleon
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.
What postcode areas do you cover around Caerleon?
Including NP18, and the surrounding Newport and Monmouthshire area.
Can I have underfloor heating?
Yes. Wet underfloor heating in the new screed is the usual choice, often with the old room's radiators kept or replaced.
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.
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.
Can you match the brick or stone on my Caerleon house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
