Patio Grow House-- this isn't made for outside /rain use, but the design/shape is what I would like for a cold frame.
Use 2×4s for the frame of the structure and 1×4s as shelves to support the aluminum rain gutters. Secure each gutter and piece of wood together with deck screws and drill ½-inch drainage holes along the bottom of every trough. Before planting up the gutters, layer the bottom with landscape fabric to prevent soil from washing out and to hold in extra moisture. #verticalvegetablegardeningideas
