Moscone West Exhibition Hall is the newest addition to the Center, expanding the facility’s conference and trade-show capacity by 45 percent. The addition’s sweeping, transparent fa?ade yields a daylight-filled building, with a 112-foot-tall curtain wall in the pre-function space forming one of California’s tallest unsupported glass structures. The building’s extraordinary flexibility, including more than 5,000 linear feet of moveable, ceiling-hung panels, allows separate events to be hosted simultaneously on all three floors. Upper floors wrap around the building’s southeast corner, extending out above the sidewalk to form a protective canopy. Gensler designed Moscone West in joint venture with Michael Willis Architects and Kwan Henmi Architecture.
