Do you need planning permission for a bungalow rear extension in Whitchurch?
Planning for a bungalow rear extension in Whitchurch follows the Welsh householder rules.
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. At the first visit we measure what is there now and tell you which route fits: permitted development or a householder planning application.
What are homes in Whitchurch like to extend?
Older terraces near the centre and post-war semis further out are typical of Whitchurch. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.
