On July 26, the Crocker Art Museum in Sacramento, California broke ground for a major addition and renovation program, designed by Gwathmey Siegel Kaufman Architects, which will triple the institution’s size to 170,000 square feet while upgrading its original landmark buildings and 1980’s addition. The project will give the museum world-class facilities and introduce a more public, iconic image.According to Crocker Art Museum director Lial Jones, “The addition will dramatically increase our gallery space to display our own collection—both historic and contemporary artworks as well as traveling exhibits. Through the years, collectors have been very generous to the museum, but currently we can only display less than four percent of what we own. We’re looking forward to expanded galleries that can display the museum’s rich holdings.“We will also be able to expand our educational programs and public amenities, allowing us to take a more active role in the community and region. We’re delighted in the way the Gwathmey Siegel Kaufman design gives the museum a more contemporary face while providing a frame for our valuable historic structures.”

The Crocker, long considered one of the cultural gems of the western United States, is the longest operating public art museum west of the Mississippi River. Like many American art museums, it started with a collection housed in the Victorian mansion of a 19th century millionaire, in this case Edwin Crocker.

In 1885, his widow presented the collection of California art, 700 European paintings and 1,000 master drawings by such artists as David, Durer and Rembrandt as well as a gallery building and grounds to the City of Sacramento. Since then the Crocker has acquired major concentrations in historic and contemporary American art, with an emphasis on work by California artists.

As the museum grew, it renovated the Crocker’s original mansion in 1924 and added a Brutalist style building in 1969. In the last expansion during the 1980’s, Edward Larrabee Barnes revamped the interior of the mansion to create a modern exhibition space and introduced a pavilion link between the two historic buildings that includes an octagonal exhibition gallery.

The Gwathmey Siegel Kaufman design sets off this ensemble with a three-story addition that links to each of the existing buildings except the1969 addition, which is being replaced as part of the project. Located on the west side of the gallery building, it stands prominently forward at the front corner of the site with a new courtyard between the old and new structures. Signaling the City of Sacramento’s interest in the project, city officials gave the museum permission to move Second Street, which borders the museum’s west side, 100 feet, affording the appropriate site area for both the courtyard and addition.

The new galleries triple the existing exhibition space, with new rooms for special exhibitions and contemporary art. Charles Gwathmey, FAIA, one of the firm’s two principals, comments, “Like many Gwathmey Siegel Kaufman additions, this plan treats the historic and new elements as a collage, with the new building acknowledging the historic precedents through quiet manipulations in scale, window placement and materials.”

The new building will introduce a two-story main entrance, museum store, café and reception area which opens out onto the courtyard. Also included are a 300-seat auditorium, public meeting rooms, education galleries and classrooms, art storage space and offices for administrative, curatorial and education staff. All of the administrative, meeting, educational and retail spaces are located on the first two floors.

Galleries occupy the entire third floor in both the new and existing buildings. They include large, flexible, 18-foot-high volumes that can accommodate large-scale contemporary art. North-facing clerestory skylights extend across these spaces, giving the roofline a distinctive silhouette.
