The institution attempted to expand its landmark building in 1978, commissioning UK architects Derek Walker and Norman Foster to design a tall tower alongside it, the first of several proposals from leading architects. But each time the effort was abandoned, because of either the cost or the design or both. To secure additional space for the museum's collections, then-director Thomas N. Armstrong III developed plans for a 10-story, $37. 5 million addition to the main building. The proposed addition, designed by Michael Graves and announced in 1985, drew immediate opposition. Graves had proposed demolishing the flanking brownstones down to the East 74th Street corner for a complementary addition. The project gradually lost the support of the museum's trustees, and the plans were dropped in 1989. Between 1995 and 1998, the building underwent a renovation and expansion by Richard Gluckman. In 2001, Rem Koolhaas was commissioned to submit two designs for a $200 million expansion. Those plans were dropped in 2003, causing director Maxwell L. Anderson to resign. New York restaurateur Danny Meyer opened Untitled, a restaurant in the museum, in March 2011. The space was designed by the Rockwell Group.
