Do you need planning permission for a wraparound extension in Bargoed?
The planning route for a wraparound extension in Bargoed is set by Wales's householder rules and your council.
Welsh side-extension rules limit a single-storey side addition to 4 metres high and a 50% increase in the width of the original house, with tighter limits in conservation areas. Wraparounds usually need a planning application.
In Wales, as in England, the Party Wall etc. Act 1996 requires notice to neighbours before work to a shared wall or excavation near their foundations.
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 Bargoed like to extend?
Bargoed 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.

Including CF81, and the surrounding South Wales Valleys area.

If you want a dining table and a sofa as well as the kitchen, usually yes.
Can you match the brick or stone on my Bargoed house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.

Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
