Do you need planning permission for a bungalow rear extension in Tonypandy?
Here is how the rules in Wales apply to a bungalow rear extension in Tonypandy.
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 Tonypandy like to extend?
Stone terraces along the valley floors and post-war semis higher up are typical of Tonypandy. Sloping sites are common, so floor levels and retaining walls are designed at the start.
