Do you need planning permission for a two-storey rear extension in Blaydon-on-Tyne?
Here is how the rules in England apply to a two-storey rear extension in Blaydon-on-Tyne.
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 Blaydon-on-Tyne like to extend?
Brick terraces, colliery houses and post-war semis make up much of Blaydon-on-Tyne. Former mining areas often need a coal mining risk check before foundations are designed.
