Do you need planning permission for a two-storey rear extension in Chadderton?
The planning route for a two-storey rear extension in Chadderton 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. 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 Chadderton like to extend?
Stone and brick terraces are common around Chadderton. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.
