In 2001, the Whitney announced another expansion plan to further increase space, this one designed by Rem Koolhaas and his firm OMA. The proposed building would be enormous, cantilevering above and over the Breuer Building. The museum kept the proposal relatively secret, and abandoned it in 2003, before any review processes, citing economics and bad timing. The board rejection prompted its director Maxwell L. Anderson to resign, compared to Armstrong III's resignation in 1990.
