The project adds management offices, a 75-person cabaret, and a 540-person reception center to the existing theatre, itself a conversion of the Philip Johnson Theaterama of the 1960 World`s Fair. The curving form of the cabaret and the cylindrical structure of the reception center complement the circular geometry of the original round building and the 1991 tower additions. The transparent curtain wall, curving sunscreens, and spherical acoustical ceiling result in a dramatic point of entry to the world of the performance and to view of the phantasmagoric remains of old Fair dreams.
A 2008–10 addition, designed by Caples Jefferson Architects with Lee/Timchula Architects, added a reception hall. A transparent circular pavilion, it is said to be "especially dramatic at twilight, when the sunset-colored, invert dome appears to hover and flow in the dark."
