Presenting a selection of models and drawings acquired by the Department of Architecture and Design since 2005—the vast majority on view here for the first time—Building Collections underscores the rationale and motives of collecting architecture at MoMA. The exhibition is organized around several themes, including ornament and abstraction, modernist urbanism and utopias, Latin American modernism, the revival of Berlin architecture since reunification, and the role of process in architecture since the digital revolution. Featured works date from 1890 to the present, and represent such diverse figures as Louis Sullivan, Le Corbusier, Bodo and Heinz Rasch, Jean Tschumi, Ant Farm, Paulo Mendes da Rocha, Sauerbruch Hutton, Barkow Leibinger, UN Studio, and Seung H-Sang of Korea.
