Do you need planning permission for a two-storey rear extension in Prestatyn?
Here is how the rules in Wales apply to a two-storey rear extension in Prestatyn.
In Wales a rear extension of more than one storey can be permitted development if the ground floor projects no more than 4 metres and the upper floor no more than 3 metres, with at least 10.5 metres to the rear boundary. It is not permitted development in conservation areas, National Parks or National Landscapes, so many double-storey schemes need a householder 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 Prestatyn like to extend?
Older terraces near the centre and post-war semis further out are typical of Prestatyn. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.
