Two-storey rear extension in Chester-le-Street

Do you need planning permission for a two-storey rear extension in Chester-le-Street?
Whether your two-storey rear extension in Chester-le-Street needs a planning application depends on its size, your house and any local restrictions.
England's rules allow a rear extension of more than one storey without an application only when it is no deeper than 3 metres and at least 7 metres from the boundary opposite the rear wall, and never on designated land. Most two-storey schemes need householder planning permission.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always 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 Chester-le-Street like to extend?
Terraces and semis are typical around Chester-le-Street. On terraces a single-storey rear extension across the back yard is usually the practical choice; semis often have room for more.
