Do you need planning permission for a two-storey rear extension in Barton upon Humber?
The planning route for a two-storey rear extension in Barton upon Humber is set by England's householder rules and your council.
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. 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 Barton upon Humber like to extend?
Red-brick terraces and semis are typical of Barton upon Humber. Coal-mining legacy areas in parts of the East Midlands can need a Coal Authority check before foundations are designed.
