Do you need planning permission for a two-storey rear extension in Gateshead?
Whether your two-storey rear extension in Gateshead needs a planning application depends on its size, your house and any local restrictions.
A two-storey rear extension can be permitted development in England only if it projects no more than 3 metres, stays at least 7 metres from the rear boundary, matches the existing roof pitch and has obscure-glazed upper side windows. In practice most double-storey rear extensions go through a householder planning application.
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 Gateshead like to extend?
Brick terraces, colliery houses and post-war semis make up much of Gateshead. Former mining areas often need a coal mining risk check before foundations are designed.
