This twenty-story mixed-use development stands on two parcels formerly occupied by a Tokyo department store.The design places the vertical service elements along the north side of the site to allow for office space within a relatively narrow site.The core and the office volume are expressed as distinct elements, and are clad in stone and glass respectively. A space of 66 feet from core to wall structures gives the curving south wall a sense of weightless suspension. Below the office space is a five-story glass volume. Extruded from the main section, it houses the retail space and is clad in an enclosure composed of vertical glass fins projecting from a clear glass wall. Rising at a height of thirty meters, it establishes an urban connection with its neighbors.
