The short answer

Do you need planning permission for a garden room in East Suffolk?

Garden rooms, offices and studios "incidental to the enjoyment of the house" are the textbook Class E case and often need no application, within limits on height, coverage and siting. In East Suffolk this matters: the borough has 52 conservation areas, and inside those the permitted development route narrows or is removed, so a garden room can need a full application where it would not two streets away.
