Do you need planning permission for a two-storey rear extension in Weybridge?
Planning for a two-storey rear extension in Weybridge 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. 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 Weybridge like to extend?
Commuter semis and detached houses make up much of Weybridge, and longer gardens make England's prior approval route for deeper rear extensions worth considering.

Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
