The Kyoto building was entirely made by students at the University of Art and Design, minimising the use of heavy machinery to lift weights, and the design of the building had to take this into account. It is a grid of paper tubes measuring 2.2x1.2m, held together by a chain of post-tensioned cables which absorb lateral thrust and improve the structure’s static activity. Each tube is jointed with special steel nodes containing eyelets for the tie rods, making the whole structure rigid enough to be perfectly isostatic.
The covering layer of polystyrene rests on sheets of plywood which collaborate in the rigidity of the lowered arch thus constructed, with storage units located at the imposts of the vault to optimise use of space.
The studio in Paris is set up in the same general way, but the arch is full, and the radius is much smaller due to problems specific to its location. The shelving is higher, so that the springer of the arch rests on them comfortably. Both structures rest on the ground, with no anchorage, as they are intended to be temporary. Technical installations run through the air space below the floor, and light is provided through apertures in the studio’s skin.
