The two 24-story towers are constructed of glass curtain wall with exposed tubular steel structure. The curtain wall is composed of nested grids. Inside, a cylindrical skylight supported by latticework draws daylight into the cubic atrium. These themes are integrated throughout the building: cube within cube, squares within squares and circles within squares.
The towers that house the offices and state-of-the-art telecommunications equipment are grounded by a five-story atrium and bridged at the top by a functional satellite and antenna platform and an observation deck.
The first four floors of the building and the connecting atrium, which feature a slanted circular glass roof, house public areas including exhibit spaces, public television studios and health club facilities.
