Do you need planning permission for a two-storey rear extension in Earlsfield?
Here is how the rules in England apply to a two-storey rear extension in Earlsfield.
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 Earlsfield like to extend?
Period terraces in Earlsfield sit alongside flats, and the difference matters: houses usually keep permitted development rights, while flats and maisonettes need planning permission for any rear extension. Two-storey rear extensions suit semi-detached houses in Earlsfield best, where the extra bedroom matters as much as the bigger kitchen.
