At the time of its completion in 2002 the One North Wacker Building incorporated solutions that were quite advanced at the time, these included an enormous glass wall of fifteen meters that confines the perimeter of the lobby space in 1.500 square meters of glass. This glass wall was a first in the United States.

Goettsch Partners was the architecture firm in charge of the architectural design.

Goettsch Partners was in charge of the architectural design, however, architecture is a complex discipline, which usually involves many professionals from different fields, without whom this building would have not been possible. We will surely be leaving out a lot of names here, but here is a list of the people we do know also played their part in making the One North Wacker Building a reality:

• Koz Sowlat in charge of Structural Engineering
• AMEC as the Main Contractor
• John Buck Company as the Main Developer
• Environmental Systems Design, Inc. in charge of MEP Engineering
• Peter Walker and Partners Landscape Architecture Inc. in charge of Landscape Architecture

The One North Wacker Building can be categorized as a Contemporary building.

The One North Wacker Building uses a frame structure made of steel columns and steel and concrete slabs.

A frame structure uses a combination of beams and columns to sustain the building's weight. The walls in this case are non-load bearing, which allows for more flexibility when distributing the interior spaces.

The facade of the building however, is load bearing. This doesn't imply that it is a traditional load-bearing wall. Rather, it means that the structure's exterior pillars have been pushed to the very edges, becoming integrated with the facade, and therefore, technically, a part of it.

From an aesthetic point of view, the facade features a glass curtain wall organized into several bays by the structural columns of the frame that have been pushed all the way out and are embedded into the facade. These columns are covered in polished steel.
