Do you need planning permission for a two-storey rear extension in Washwood Heath?
Planning for a two-storey rear extension in Washwood Heath follows the English householder rules.
England's rules allow a rear extension of more than one storey without an application only when it is no deeper than 3 metres and at least 7 metres from the boundary opposite the rear wall, and never on designated land. Most two-storey schemes need householder planning permission.
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 Washwood Heath like to extend?
Washwood Heath has a lot of post-war semis and estate houses with long gardens and side access, which makes rear extensions quicker to build.
