On January 18, 1995, the San Francisco Museum of Modern Art moved into its current building, designed by the Swiss architect Mario Botta. With fifty thousand square feet of exhibition space, the facility has proven to be an exceptional setting for the presentation of modern and contemporary art. Over the years, however, our collection has expanded at an ever-accelerating pace. Seeking ideas for the display of our growing number of large-scale sculptures, we invited six innovative Bay Area firms — Mark Cavagnero Associates, envelopeA+D, Fougeron Architecture, Jensen & Macy Architects, Kuth/Ranieri Architects, and Pfau Architecture — to participate in a competition. Their brief: to transform the roof of the SFMOMA Garage into a sculpture garden accessible from our fifth-floor galleries.
