Do you need planning permission for a two-storey rear extension in Consett?
Whether your two-storey rear extension in Consett 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 Consett like to extend?
Brick terraces, colliery houses and post-war semis make up much of Consett. Former mining areas often need a coal mining risk check before foundations are designed.
