In the first years of independent practice David Hotson began a long period of collaborations with Yale classmate Maya Lin, acting as the executive architect on a series of projects that she attracted as her Vietnam Veterans Memorial –designed while she was an undergraduate at Yale- was completed to wide acclaim. Early projects included the Museum for African Art in SoHo, a suite of offices and galleries for the Asia/Pacific-American Institute at New York University, and an apartment for software entrepreneur and art-world philanthropist Peter Norton. From these early collaborative experiences the office has developed an extensive track record of working in association with artists, designers, and other architects to execute projects with demanding detailing and progressive design values. The body of collaborative work undertaken by the office has included projects with noted architects such as David Adjaye of London, Santiago Calatrava of Valencia and Zurich, Hayaki Kita of Osaka, and Ricardo Legorretta of Mexico City, and other architects, artists, and designers based in the US, the UK, the Netherlands, Germany, France, Spain, Switzerland, Hungary, Armenia, and Japan. Among these international collaborations was the renovation of the Offices of the Secretary General of the United Nations, for which David Hotson was the executive architect.
