77 West Wacker Drive, previously the United Building, now called "The Bamboo Forest" is an American office building in the Loop, Chicago. Finished in 1992, the building rises to a height of 668 ft (204 m) with around 944,000 square feet (87,700 m2) of interior space. The building, with 50 floors, was designed by Ricardo Bofill Taller de Arquitectura. It was formerly known as the RR Donnelley Building when RR Donnelley was the primary tenant. RR Donnelley moved its corporate headquarters to a different location in May 2005, and in 2007 the building became the corporate headquarters of United Airlines. The deal included naming rights to the building.
The building was the world headquarters of Chicago-based United Airlines and its parent company, United Continental Holdings. It also served as the headquarters for United Continental subsidiary Continental Airlines until its certificate was merged with United on November 30, 2011. In 2012, United moved its headquarters to the Willis Tower, where the company occupies around 20 floors.
Archer Daniels Midland moved its headquarters to the building in August 2014 from Decatur, Illinois. The building has a newsletter called "FOCUS", published by Prime Group Realty Trust.
By 1990, Keck, Mahin & Cate, a then-prominent Chicago-based law firm, considered moving out of its space in the Sears Tower and moving into a potential new development, which would become 77 West Wacker Drive. Brokers who were familiar with the lease negotiations stated that Sears was trying to keep Keck, Mahin & Cate in the building. Keck, Mahin & Cate decided to move into 77 West Wacker, and the Prime Group, developer of 77 West Wacker, finalized the development of the facility. In 1991, RR Donnelley leased 215,000 square feet (20,000 m2) on floors 9 through 19 for its world headquarters, and Kemper Securities leased 150,000 square feet (14,000 m2).
With the lease deals concluded, 77 West Wacker had 86% of its tenant space occupied. Jerry C. Davis of the Chicago Sun-Times said that the remaining space would be too small for some prospective tenants. Davis added that the leases to RR Donnelley and Kemper significantly altered "the complexion of the downtown office market." Keck Mahin & Cate moved from the Sears Tower to 77 W. Wacker in mid-1992; the firm suffered a series of practice group defections and questionable management decisions, and ultimately ceased operation in 1997.
In 2004, RR Donnelley signed a letter of intent to move out of 77 West Wacker. During the same year, McGuireWoods extended its lease by 8 years, changing the end date from December 31, 2010 to December 31, 2018. In addition, McGuireWoods expanded its leased space, effective February 1, 2004. The company gained an extra 65,756 square feet (6,108.9 m2) of space in addition to its existing 67,819 square feet (6,300.6 m2). As a result of the lease expansion of McGuireWoods, as of February 2004, 77 West Wacker was 92.2% leased. In 2004, the lease of the firm Jones Day of 138,764 square feet (12,891.6 m2) in 77 West Wacker was extended by 15 years, with the end date changed from September 30, 2007 to September 30, 2022. In 2006, Microsoft extended the term of its lease and expanded its leased space to 12,391 square feet (1,151.2 m2), with a total of 47,122 square feet (4,377.8 m2) occupied by Microsoft. During the same year, Greenberg Traurig agreed to expand its lease by 22,565 square feet (2,096.4 m2), giving it a total of 100,975 square feet (9,380.9 m2).
In 2006, United Airlines agreed to move its 350 executives and some staff members from its Elk Grove Township campus to 77 West Wacker.
On August 13, 2012, United Continental Holdings announced its intention to once again relocate its world headquarters. An agreement was reached for United Continental Holdings to lease an additional 200,000 square feet (19,000 m2) at Chicago's Willis Tower, joining the airline's operations center which leased an initial 470,000 square feet (44,000 m2) in 2010. The company vacated the majority of their offices at 77 W. Wacker with the naming future of the building left unknown.
77 W. Wacker is one of the most prominent examples of postmodern architecture in the city of Chicago. The facade consists of glass surfaces framed in Portuguese white granite, with the dividers between the different floors linked by columns. The top floor is shaped like a Greek pediment. The ground floor houses a 59-foot-high (18 m) atrium in gray and white marble. To enhance its panoramic view over the city, the building's skin is predominantly glazed.
The interior is similarly styled. The classical Greek style is repeated inside, with Thassos marble walls and a 40 ft (12 m) tall coffered ceiling made of white oak wood.
A sculpture by Xavier Corberó called "Three Lawyers and A Judge" graces the building, as does Antoni Tàpies' artwork called "Big Eyelids". Bofill further contributed by creating a sculpture entitled "Twisted Columns" which appears to float above a reflecting pool. At night, 540 lamps light the building and its surroundings, along with a United sign that was added to the building in 2008.
Steve Baron, president of Prime Group Realty, said in 1990 that 77 West Wacker had "very compact floors with virtually no columns." Therefore, tenant companies would not pay for space that they would be unable to use.
Chicago Transit Authority (CTA) bus lines serving the building include 22, 24, 29, 62, 124, 146 and 151. The closest Chicago 'L' stations are Clark/Lake, serving the Orange, Green, Blue, Purple, Pink and Brown Lines, and the State/Lake station, which serves the Orange, Green, Purple, Pink and Brown Lines, with a connection to the Red Line at Lake.
