Planning rules for Pontypool
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.
Welsh building regulations apply to every rear extension. The council or a registered approver checks the work against the Welsh Approved Documents and issues a completion certificate.
