Do you need planning permission for a two-storey rear extension in Walsall?
Here is how the rules in England apply to a two-storey rear extension in Walsall.
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 Walsall like to extend?
Red-brick terraces and 1930s semis make up much of Walsall. Many already have a small kitchen lean-to at the back, which a new rear extension usually replaces rather than adds to.
