Do you need planning permission for a two-storey rear extension in Royal Leamington Spa?
Planning for a two-storey rear extension in Royal Leamington Spa follows the English householder rules.
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 Royal Leamington Spa like to extend?
Royal Leamington Spa has a lot of post-war semis and estate houses with long gardens and side access, which makes rear extensions quicker to build.
