2018 Tod Williams and Billie Tsien

Tod Williams & Billie Tsien began working together in 1977 and co-founded their architectural practice in 1986. Located in Midtown Manhattan, their studio focuses on work for institutions including schools, museums, and not-for-profits—organizations and people that value issues of aspiration and meaning, timelessness and beauty. They believe that architecture is the coming together of art and use. Their buildings are carefully made from the inside out to be functional in ways that speak to both efficiency and the spirit. A sense of rootedness, light, texture, detail, and most of all, experience, are at the heart of what they design. From the early sketches through construction completion, they are personally involved in every project their studio takes on.

Over the past three decades they have received numerous national and international citations. Outside the studio, they are active participants in the cultural community and have long-standing associations with many arts organizations. Parallel to their practice, they maintain active academic careers and lecture worldwide. As both educators and practitioners, they are deeply committed to making a better world through architecture.
