Do you need planning permission for a terraced house rear extension in Caldicot?
Here is how the rules in Wales apply to a terraced house rear extension in Caldicot.
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.
The Party Wall etc. Act 1996 also applies in Wales: two months' notice for work to a shared wall and one month for foundations dug close to a neighbour's building.
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 Caldicot like to extend?
Older terraces near the centre and post-war semis further out are typical of Caldicot. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.
