Do you need planning permission for a kitchen-diner rear extension in Deeside?
Planning for a kitchen-diner rear extension in Deeside follows the Welsh householder rules.
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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Deeside like to extend?
Older terraces near the centre and post-war semis further out are typical of Deeside. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.
