In 1971 he was commissioned by John Hauberg and Anne Gould Hauberg to develop designs for the Pilchuck Glass School. Bosworth drew on the rustic architecture of the American West as a source for his design of the Hot Shop for kilns for glass blowing (1973), Flat Shop for smaller glass projects (1976), Lodge (1977), and a series of other structures. By 1986 he was responsible for fifteen structures at Pilchuck. He also served as Director of the school from 1977 to 1980.
