Although originally planned as brick-clad, the facade material was changed to aluminium and eventually to stainless steel in 7,000 panels with a three-dimensional treatment that gives the facade a "rusticated" effect. The building is set on a three-storey base clad in blue glass, with retail spaces and through-building arcades. The lobby is vaulted, reflecting the arched entrances, and has white marble and terrazzo decor.
