Do you need planning permission for a bungalow rear extension in Llanelli?
Here is how the rules in Wales apply to a bungalow rear extension in Llanelli.
In Wales a single-storey rear extension can often be permitted development if it projects no more than 4 metres beyond the rear wall and is no more than 4 metres high. Wales has no prior approval route for deeper extensions, so anything bigger needs a householder planning application.
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 Llanelli like to extend?
Older terraces near the centre and post-war semis further out are typical of Llanelli. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.
