Do you need planning permission for a two-storey rear extension in West Ealing?
Planning for a two-storey rear extension in West Ealing 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 West Ealing like to extend?
Period terraces in West Ealing sit alongside flats, and the difference matters: houses usually keep permitted development rights, while flats and maisonettes need planning permission for any rear extension.

Is the site visit in West Ealing free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
