Gaviidae Common is a mixed-use shopping mall and office complex on Nicollet Mall in Minneapolis, Minnesota. The first phase of the mall, Gaviidae Common I, opened in 1989 and is adjoined to Gaviidae Common II by a series of skyways. Phase II opened in 1991. A joint venture designed by Argentine American architect César Pelli and Chicago-based Lohan Associates, the mall occupies 443,000-square-foot (41,000 m2) of retail and office space spread across five floors. Following the closure of the mall's food court and several tenants in 2013, the top three floors of Gaviidae Common II were converted into office and recreational space for the adjoining RBC Plaza.
