Bill & Melinda Gates Foundation NBBJ

A local firm with a global practice rethinks the headquarters for the world’s largest charitable foundation. 

Seattle

The new headquarters occupies a prominent site, across Fifth Avenue from the Seattle Center, where the 1962 World’s Fair took place and the Space Needle rises. In 2000, the Frank Gehry–designed Experience Music Project (EMP) opened, bringing new energy to a part of town that had grown seedy after the fair closed. The 12-acre Gates campus reinforces the area’s comeback, while adding a more buttoned-down sensibility. A pair of curved office buildings, a reception pavilion, and a 1,000-car parking structure anchor three corners of the site and may be joined by a third office building in the future. By burying four of the garage’s five levels below grade and creating a plaza in front, NBBJ tamed the impact of the huge structure. A visitor center designed by Seattle-based Olson Kundig Architects occupies part of the garage’s frontage on Fifth Avenue, adding another hospitable note to the structure.


Early in the design process, the architects and client decided that a campus was the right model for the project. So they broke the complex into a set of four buildings and collaborated with Seattle-based Gustafson Guthrie Nichol on the landscape. Weaving buildings and landscape together was an essential part of the scheme, says Christian Carlson, NBBJ’s lead designer for the project. To take advantage of a climate that is temperate most of the year, the design team created a large plaza one level below the street. (Dropping the plaza below grade allowed the architects to add an extra floor to the office buildings without exceeding the height limit, which is measured from the street.) On nice days, foundation employees work on laptops and socialize here. A shaded courtyard next to the reception pavilion offers views to the plaza below, providing a degree of transparency to people even if they don’t have any further access.
The project earned a LEED Platinum rating by applying a range of sustainable strategies, including landscaping and green roofs that cover 40 percent of the site; a 1 million-gallon tank that stores rainwater for use in irrigation, reflecting pools, and toilets; a 750,000-gallon underground tank for water to chill the buildings, and aggressive daylighting made possible by narrow buildings that keep all workstations within 30 feet of sunlight.


A multistory atrium at one end of the north office building serves as a civic space where employees can eat lunch, work on laptops, or gather for special presentations. A floor-toceiling glazed corridor running along the plaza side of each office building lets people see their colleagues from afar and feel connected, says Melissa Milburn, who handles external communications at the foundation. “It’s like Hollywood Squares. We can see who’s here.” Open “hubs” at the elbow of each floor and a variety of casual spaces encourage chance encounters and socializing. Forty-four years ago, Kevin Roche built the iconic Ford Foundation in New York around a hushed indoor garden. NBBJ has updated that model, wrapping the Gates complex around a lively outdoor plaza and greening its roofs.
