Do you need planning permission for a glazed rear extension in Rhyl?
Here is how the rules in Wales apply to a glazed rear extension in Rhyl.
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.
Wales has its own Approved Document L, with targets for walls, roofs, floors and glazing similar to but not identical with England's. Heavily glazed designs are checked with a calculation.
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 Rhyl like to extend?
Older terraces near the centre and post-war semis further out are typical of Rhyl. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.
