Do you need planning permission for a bungalow rear extension in Haverfordwest?
Whether your bungalow rear extension in Haverfordwest needs a planning application depends on its size, your house and any local restrictions.
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 Haverfordwest like to extend?
Older terraces near the centre and post-war semis further out are typical of Haverfordwest. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.
