Do you need planning permission for a two-storey rear extension in Taunton?
The planning route for a two-storey rear extension in Taunton is set by England's householder rules and your council.
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 Taunton like to extend?
Stone-built and rendered houses are common around Taunton, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.
