111 South Wacker Drive
Chicago, Illinois / United States of America
111 South Wacker was designed as a state-of-the-art multi-tenant office tower. The enclosure systems were used to express structure and technology, still the essential components of today's high-rise construction. The building's office space is positioned above seven floors of structured parking. The typical office floors are column-free, with 50- and 60-foot lease spans between the center core and the perimeter columns. This layout allows for optimal efficiency and flexibility, which remain critical drivers of today's office buildings. Between the columns, the building is enclosed with a curtain wall system with stainless steel V-shaped mullions that complement the vertical expression of the column cladding. Although the footprint of the building's upper floors occupies almost the entire site, the building is open and spacious at street level. The openness of the lobby is enhanced by the cable-supported, water-white, non-reflective glass enclosure; the first elliptical cable-net wall in the world. Floor and ceiling patterns reflect the parking ramp above, creating a consistent, dynamic rhythm that energizes the space. 111 South Wacker was designed from the outset with an emphasis on sustainability and LEED certification in mind. As a result of the sustainable design initiatives, it was the first building ever certified LEED-CS Gold.
