The five-story, 34,000 square foot Science + Engineering [STREAM] Building is the newest addition to the Seattle Academy of Arts + Sciences campus. Located at the corner of 13th and East Spring on Capitol Hill, the STREAM building consists of seven laboratory and studio classrooms, a two-story learning commons, and associated staff offices. The design incorporates a mix of flexible formal and informal learning environments to encourage student-initiated projects, collaboration and innovation.

To exceed LEED Gold standards, the building utilizes power from photo-voltaic panels and features a green roof atop a new breezeway, connecting the existing Arts building to the STREAM building. Additional sustainable features include a 12,000 gallon cistern for rain water harvesting, hydronic ceiling panels, radiant heat floors, and passive cooling.
