The main floor of the 55,000-square-foot building is divided into five equal-sized, parallel pavilions. The side walls are clad in two-inch wide slabs of Italian travertine, entirely concealing the facility’s environmental and security systems and providing a quiet setting for the presentation of sculpture. The facades at each end are fabricated from clear glass, allowing the pavilions to visually extend into the garden and creating a seamless continuity between the Center’s indoor and outdoor spaces.
A unique barrel-vaulted glass ceiling is suspended above the galleries, atop narrow steel ribs and supported by thin, stainless steel rods. An innovative cast aluminum sunscreen, specifically designed for this project (patent pending), floats above the roof and allows controlled natural light to filter into the galleries, eliminating the need for artificial illumination much of the time.
The three central pavilions on the main floor serve as galleries for the display of smaller and environmentally-sensitive sculptures, as well as related paintings, prints, and drawings from the Nasher Collection. The two outer pavilions house a cafe and store, while the lower level will include a smaller gallery for the display of light-sensitive works, a conservation lab, educational and research facilities, and an auditorium that opens to an outdoor terraced garden.
