What is a new build home?
A new build home is a house built from the ground up on a cleared plot, a garden plot or a replacement-dwelling site. We work with plot owners and self-builders to design, gain approvals and build the house, either to a fixed design or from initial ideas.

Do you need planning permission for a new build home in Risca?
Approvals for a new build home in Risca follow the rules for Wales. In Wales a new home needs full planning permission. Welsh building regulations require automatic fire suppression (sprinklers) in new homes, and sustainable drainage approval from the council’s SuDS approval body is needed for most new buildings.
Building regulations in Wales are set by the Welsh Government. Approval comes from the council’s building control service or a registered building control approver, with inspections during the work and a completion certificate at the end.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
