With high-profile museum projects recently completed or in the works in several countries, Selldorf Architects has become a leading choice as a design practice for institutions looking to expand and transform their existing buildings. But several projects of the New York-based firm, founded by Annabelle Selldorf in 1988, have faced intense controversy over their designs. This onslaught includes everything from public outcry and a petition to halt its work to rebukes by leading professionals in projects ranging from the Frick Collection in New York to the Museum of Contemporary Art San Diego and the National Gallery in London—the latter two comprising previous additions designed by Robert Venturi and Denise Scott Brown. Selldorf, in conversation with RECORD editor in chief Josephine Minutillo, defends her schemes.
