A branch screen. remember idea: branch screens, built in planter boxes on rolling casters. Creates a moveable screen, with independent ivy growth-bonus boints for creating hinged, double screen frames that will collapse for moving or customizable sizes
I love the little stepping stone path (maybe impractical?) and also the way the screens stop you seeing all the way down - draws your eye along path (could be a good way to distract attention from fence and wall?
