Do you need planning permission for a garden annexe in Poulton-le-Fylde?
The approval route for Poulton-le-Fylde is set by planning law in England. In England an annexe used as living accommodation usually needs planning permission. Outbuildings built under permitted development must be incidental to the house, such as a gym or office, not a bedroom.
