UBS Tower

One North Wacker, formerly UBS Tower is a 199 m (653 ft) skyscraper located at One North Wacker Drive in Chicago, Illinois. The 50 story structure, started in 1999 and completed in the spring of 2002, was designed by Lohan Associates (now Goettsch Partners) with developer the John Buck Company to accommodate the needs of UBS groups such as UBS Warburg, UBS PaineWebber, UBS Global Asset Management and UBS O’Connor in a single building.


The UBS Tower was the first large multi-tenant tower to be constructed in Chicago for 6 years since 1993.


The tower's most eye-catching feature is its main lobby. The lobby's glass wall was a first in the United States. The 40-foot (12 m) wall was made out of 5'x5' glass panes attached to a system of medallions and cable. This cable system was tested at pressures above 150 psf, or a wind speed of nearly 250 mph. The glass itself is also noteworthy- an optical interference anti-reflective glass (designed by Schott AG) with an unusually low surface reflectivity of 1% is used. This imbues the lobby with an almost transparent appearance.

Exterior landscaping was designed by the Berkeley, Calif.-based firm, Peter Walker and Partners Landscape Architecture Inc.


Artwork throughout the building is drawn from the UBS PaineWebber Collection of contemporary art pieces and from the UBS Global Asset Management collection of architectural relics. Roy Lichetenstein’s sculpture, Archaic Head, is displayed on the 38th floor near Louis Sullivan’s elevator gate, claimed from the old Chicago Stock Exchange.


With 1,754,000 square feet (163,000 m2) of floorspace, UBS Tower's rents are among the highest per square foot of any building in the Chicago Metropolitan Area at an average of over $25 per square foot on a triple net basis, grossing up to over $40 per square foot. The building amenities also include a two story underground garage for senior executives, One North Kitchen and Bar, a Conference Center, Fitness Center and Convenience Store.


In March 2002, the building was recognized as “Development of the Year” at the 14th Annual Greater Chicago Commercial Real Estate Awards.
