Do you need planning permission for a two-storey rear extension in Newton Aycliffe?
The planning route for a two-storey rear extension in Newton Aycliffe is set by England's householder rules and your council.
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. 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 Newton Aycliffe like to extend?
Terraces and semis are typical around Newton Aycliffe. On terraces a single-storey rear extension across the back yard is usually the practical choice; semis often have room for more.
