SFMOMA’s leadership worked closely with Snøhetta to create a transformational expansion that incorporates and renovates the museum’s existing Mario Botta–designed building, which debuted in 1995. The new museum accommodates the significant growth of SFMOMA’s collection, program and visitorship, nearly tripling the museum’s gallery space, including nearly 45,000 square feet of free public-access space and weaving SFMOMA into its urban setting as never before.


The project was conceived to create a more open and welcoming SFMOMA, with the volume of the expansion rising up behind the Botta building and stretching the full city block from Minna Street to Howard Street. This placement activates existing mid-block streets as pedestrian pathways and opens up new entrances, deeply integrating the museum into the South of Market (SoMa) neighborhood, including nearby Yerba Buena Gardens and the Moscone Center.

Two entrances on Third and Howard Streets connect visitors to free ground-floor exhibition spaces, inaugurated with a presentation of Richard Serra’s monumental sculpture Sequence (2006) in the Roberts Family Gallery, where the museum will present commissioned works in the future. The Joyce and Larry Stupski Entrance at Minna Street welcomes school groups to the Koret Education Center, as well as visitors attending in the Phyllis Wattis Theater and the Gina and Stuart Peterson White Box.

The pathways from all three public entrances converge at the second-floor Helen and Charles Schwab Hall, a spacious gathering place with views to the Pat and Bill Wilson Sculpture Terrace and the museum’s new vertical garden, the largest public living wall of native plants in the United States. In Helen and Charles Schwab Hall, visitors may pass from the free ground-floor exhibition spaces into the second-floor and upper floors of ticketed galleries for the permanent collection and special exhibitions.

The expansion provides galleries well-tailored to the collections on view, and the gallery design rigorously eliminates visual clutter and emphasizes simplicity. Special areas within the expansion include designated spaces for the:
- Pritzker Center for Photography: 15,000 square feet of gallery, study and interpretive space—the largest gallery and interpretive space in a U.S. art museum permanently dedicated to photography.
- Doris and Donald Fisher Collection Galleries: 60,000 square feet of gallery space on three floors dedicated to selections from one of the most outstanding collections of postwar and contemporary art in the world, as well as an additional gallery on the third floor dedicated to works by Alexander Calder from the Fisher Collection, generously supported by Barbara and Gerson Bakar.
- Mimi and Peter Haas Galleries: 8,800 square feet showcasing a rotating selection of contemporary art in a loft-like gallery, framed by extensive city views from the adjacent outdoor terrace
- Architecture and Design: two galleries providing 3,500 square feet dedicated to the museum’s important holdings of architecture and design, as well as special exhibitions.
- Media Arts: two galleries providing 4,400 square feet of gallery space reserved for rotating and special exhibitions from the museum’s media arts collection.
New Work: a 1,100-square-foot gallery permanently dedicated to showcasing emerging artists selected by the museum’s four curatorial departments.
- Koret Education Center: a 4,800-square-foot education center including a resource library and two classrooms.
- Performances and Events: the Gina and Stuart Peterson White Box, a flexible, double-height space, along with the museum’s upgraded Phyllis Wattis Theater provide locations for a wide range of performances and events.
Elise S. Haas Conservation Studio: a new two-story, 4,200-square-foot conservation center, adjacent to exhibition galleries with exceptional natural light, reveals to the public some of the museum’s vital work in this field, while also providing a studio space for artists.
Library and Archives: a new 4,000-square-foot space for the museum’s extensive library and archives, containing nearly 250,000 objects, available to scholars and researchers by appointment.
Administrative Offices: office space for the museum’s administrative staff

- The façade of the Snøhetta expansion, inspired in part by the fog and the waters of the San Francisco Bay, comprises more than 700 uniquely-shaped FRP (fiberglass-reinforced polymer) panels affixed to a curtain-wall system to create rippling horizontal bands which appear to shift in appearance with the changing light.
- The maple-faced Roman steps in the Roberts Family Gallery, overlooking Richard Serra’s monumental work, Sequence (2006), offer one of San Francisco’s liveliest new public gathering places.
- A new sculptural staircase designed by Snøhetta leads visitors from the Evelyn and Walter Haas, Jr. Atrium to the second floor. Located beneath Botta’s iconic oculus and Alexander Calder’s mobile Untitled (1963), it replaces the original 1995 stair. Opening up the space, the new, sculptural stair helps make a seamless connection between the existing and new buildings and accommodates the occupancy needs of the expanded museum.
- Six outdoor terraces provide spaces for installations of sculpture, and from the seventh floor highlight a dramatic view of the San Francisco cityscape.
- The largest public living wall in the United States provides a background for sculpture on the third floor terrace. With over 19,000 plants, including 21 plant species native to California and the Bay Area, the living wall is an ever-changing work of natural art supported with a recycled water system.
- SFMOMA has partnered with Bay Area innovator Meyer Sound to install sound solutions throughout the museum, including a state-of-the-art Constellation acoustic system in the newly renovated Phyllis Wattis Theater. Constellation provides the space with the utmost flexibility and intelligibility, establishing Wattis Theater as a premier arts venue in the Bay Area.
