Billie Tsien, with Tod Williams, founded Tod Williams Billie Tsien Architects in 1986. Their studio, located in New York City, focuses on work for institutions—museums, schools, and non-profits; organizations that value issues of aspiration and meaning, timelessness, and beauty. Their buildings are carefully made and useful 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 build. Their compelling body of work includes the Natatorium at the Cranbrook School, the American Folk Art Museum in New York, the David Rubenstein Atrium at Lincoln Center, the Asia Society Center in Hong Kong, the Logan Center for the Arts at the University of Chicago, the Barnes Foundation in Philadelphia and the new LeFrak Center in Brooklyn's Prospect Park. The firm, with Davis Brody Bond, was awarded the commission to design the New Embassy Compound in Mexico City. Parallel to their practice, Williams and Tsien maintain active teaching careers and lecture worldwide.
