This formation allows the balcony being an extensive garden and a useful resting place at the same time using the impressions of the port and the buliding itself. When needed, you raise the supporters, hang the canvas on them and the seat is ready, otherwise they are hidden in the floor.
The planting needs 5-6 cm poor soil, sometimes a little water, and that's all (no cutting) and if you step on them, it doesn't matter, the broken pieces will root soon.
Hangarden is a hangig garden - garden on a building, far from the natural ground - and the seat is just a hanging canvas, that easily fits the body of the user so that makes a very comfortable posture.
