Do you need planning permission for a two-storey rear extension in Great Yarmouth?
Planning for a two-storey rear extension in Great Yarmouth 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. 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 Great Yarmouth like to extend?
Great Yarmouth mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.
