The structure consists of 4 bundled tubes, similar to the Sears Tower except that these are hexagonal instead of square.
Each of the tubes has a sloping roof. Penthouse units feature greenhouses and outdoor terraces.
Located at the inside corner of the Gold Coast streetwall where Lake Shore Drive turns east and the "Magnificent Mile" (Michigan Avenue's glamorous shopping and hotel district) begins.
The wall and ceiling lamps in the lobby are clusters of hexagonal tubes, like the building's structure.
Early plans by the building's developer called for a six-level retail mall at the base.
The hexagonal tubes were choses in part because they could be parallel both to the city's street grid and to Oak Street Beach at the same time.
The tubes' heights were calculated to minimize afternoon shadows on the beach.
In most of the apartments one room is a pentagon, allowing the remaining space in each unit to fit 90° angles.
In 1984 this building won the Best Structure Award from the Structural Engineers Association of Illinois.
