Designed by kengo kuma and associates, the façade of the building is covered with planters made of aluminum die-cast panels, which provides space for facilities.
The 3 (up to 6) aluminum panels, which also form planters, are made in monoblock casting. Each panel is slanted, and its surface appears to be organic, of which cast comes from decayed styrene foam.
Equipment such as watering hose, air reservoir for ventilation and downpipes are installed behind the panels so that the façade can accommodate a comprehensive system for the building.
The project covers a 1,052 m² area.
