"It's hard to miss San Francisco's new U.S. Federal Building, a narrow 18-story office slab with a skewed, not-quite-mansard roof. Completed in March of last year, the building is a study in contradictions: an ambitious energy-conserving agenda, a tight budget, and a highly restrictive set of security concerns. How did Pritzker Prize-winning architect Thom Mayne deal with this challenging mix?

The first impression of the Federal Building, which is in the South of Market district, is somewhat intimidating. Its inscrutable facade is shrouded in a perforated-stainless-steel scrim, which is mysteriously sliced and peeled away, apparently at random. At the base of the building, the screen mutates into a folded roof that covers what appears to be a greenhouse but is actually a day care center. The imposing pavilion in the foreground, whose complicated roof resembles a trestle bridge, turns out to be a coffee shop. As often happens in a Mayne design, many things are not what they seem."
