Do you need planning permission for a bungalow rear extension in Caerleon?
The planning route for a bungalow rear extension in Caerleon is set by Wales's householder rules and your council.
Welsh permitted development allows a single-storey rear extension of up to 4 metres in depth and 4 metres in height, subject to boundary and garden-coverage limits. There is no larger-extension prior approval scheme in Wales.
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 Caerleon like to extend?
Caerleon has Victorian terraces near the centre and semis further out. Welsh permitted development allows up to 4 metres at the rear for many houses.

Yes. We apply to the council or a registered approver under the Welsh regulations and hand over the completion certificate.
Will I need a structural engineer?
