Do you need planning permission for a two-storey rear extension in Battersea?
Here is how the rules in England apply to a two-storey rear extension in Battersea.
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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Battersea like to extend?
Much of Battersea is Victorian and Edwardian terraced housing with narrow back additions, which suits side returns, wraparounds and 3 metre rear extensions. Many streets are in conservation areas, gardens are short, and almost everything comes through the house or along a rear alley. Two-storey rear extensions suit semi-detached houses in Battersea best, where the extra bedroom matters as much as the bigger kitchen.
