The Pritzker-prize winning architect Thom Mayne has been identified with muscular, bold, steel-and-glass design since the founding of his firm, Morphosis, in 1971. With the Federal Office Building in San Francisco, Mayne proves that innovative and sustainable architecture can be introduced successfully into a building type typically considered predictable and boring. In this tour of the dramatic high-rise building, Mayne takes us through its many awe-inspiring spaces, including the main lobby, upper-level offices, and an elevated outdoor bridge. During the compelling visit, the architect's engaging remarks about various green features also provides added insight into the building's inner workings. Producer: Edgar B. Howard.
