The massive 26-story Builders Building once featured showrooms of construction materials and techniques. The original design, a limestone and terra cotta office building wrapped around a central atrium, is fairly standard. But a curious 1986 renovation extended the building east along Wacker Dr. The addition added floors and a sloping glass wall resembling an oversized mansard roof. The building's tall, elegant lobby doubles as a space for events.
