Do you need planning permission for a two-storey rear extension in Halesowen?
Whether your two-storey rear extension in Halesowen 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. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Halesowen like to extend?
Halesowen has a lot of post-war semis and estate houses with long gardens and side access, which makes rear extensions quicker to build.
