Concrete technology takes another small and surprising leap, even by exacting Japanese standards, in this delicately perforated pod-for-all-occasions designed by Kazuya Morita. The secret of this remarkable little structure lies in its material and construction. The concrete is fibre-reinforced, a combination of white cement, lightweight aggregate and glass fibre. This mixture was meticulously hand trowelled onto a carved styrofoam mould by skilled plasterers (the traditional Japanese plasterer's art is known as sakan). The perforations were created by attaching styrofoam rings to the dome-shaped master mould. When the concrete hardened, the mould was dismantled and removed.
