111 South Wacker

Chicago, Illinois

111 South Wacker is designed as a Class A multitenant office tower. 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, optimizing efficiency and flexibility.

While the footprint of the building’s upper floors covers almost the entire site, the building is open and spacious at street level. To create this sense of space, the perimeter tower columns transfer through the parking floors to provide large, 80-foot spans at the base. The openness of the lobby is dramatically enhanced by the cable-supported, non-reflective glass enclosure and a very compact core. The result is the feeling that the ground floor is a covered outdoor plaza. Floor and ceiling patterns reflect the parking ramp above, creating a consistent, dynamic rhythm that energizes the space.

The enclosure systems are used to express structure and technology, the essential components of today’s high-rise construction. The building is enclosed with a unitized curtain wall system with high-performance glass and featuring stainless steel V-shaped mullions that reinforce the vertical expression of the column cladding.

The building was designed from the outset with an emphasis on sustainability and LEED certification in mind. As a result of the sustainable design initiatives, the building became the first ever to be certified LEED-CS Gold.
