Do you need planning permission for a bungalow rear extension in Risca?
Here is how the rules in Wales apply to a bungalow rear extension in Risca.
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 Risca like to extend?
Stone terraces along the valley floors and post-war semis higher up are typical of Risca. Sloping sites are common, so floor levels and retaining walls are designed at the start. For Risca bungalows we design the roof first, because the low eaves decide the height of the new room.
