What is a small housing development?
A small housing development is a scheme of a few new homes, typically two to nine, on a single site. We work with landowners, small developers and investors to build schemes that already have planning permission, or help take a site through planning first.

Do you need planning permission for a small housing development in South Glamorgan?
Before anything is built in South Glamorgan, we confirm which approvals apply in Wales. In Wales small schemes need full planning permission and, for most new buildings, sustainable drainage approval from the SuDS approval body. New homes must have sprinklers.
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.
