Do you need planning permission for a terraced house rear extension in Pontypridd?
Here is how the rules in Wales apply to a terraced house rear extension in Pontypridd.
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.
In Wales, as in England, the Party Wall etc. Act 1996 requires notice to neighbours before work to a shared wall or excavation near their foundations.
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 Pontypridd like to extend?
Stone terraces along the valley floors and post-war semis higher up are typical of Pontypridd. Sloping sites are common, so floor levels and retaining walls are designed at the start.
