The 15-storey building provides space for members of the China Diamond Exchange, as well as other related and speculative tenants. In addition to office space on the upper levels, the building includes retail on the ground floor and a second floor that features the elevator lobby, exhibition space and a restaurant.
The building is conceived as two rectangular office slabs connected by an atrium, with a large, 66- by 230-foot cable-supported net wall at each end. One tower is fully dedicated to the Diamond Exchange members and designed to provide them with secure transport from their below-grade parking spaces to their offices above. The adjacent tower serves the other tenants, with access through an open elevator tower in the centre of the atrium.
The major tenants’ core business inspired the design, with diamond-shaped elements featured throughout. References are seen most prominently in the atrium’s glass skylight, the structural geometry of the entry canopy, and the main lobby floor.
The color palette of black, grey and red dominates the building. The office slabs are treated in black, including the horizontal grille at the ends, which provides a surface that disguises the intakes and exhausts of the mechanical system.
The open elevator tower defines the focal point of the building, with three cabs traversing the atrium to sky bridges on each level that connect the two office blocks. The elevators’ activity is not only visible from the lobby but also from outside, through the cable-supported net walls running the full height of the building.
