I ride down Mission Street everyday, and I always admire the JP Morgan Chase building at 560 Mission between First and Second Street. Most buildings in downtown SF are earth-toned, and riding among them can feel like flashing back to the Gap in the early 90's — putty, mauve, beige, taupe, moss. In contrast, the Morgan building has black steel-and-glass facade with a greenish tint, pleasantly blending erector-set orderliness with an aquarium-like glow. Today I found out it was designed by Cesar Pelli, aka the guy/firm behind the Petronas Towers. Each architect in this review of recent architecture in the SF Business Journal describes 560 Mission as their favorite recent SF project.
