When the design team at Jensen Architects first considered the idea of using dichroic glass in the renovation of a 1980sera office building for a technology company, principal Dean Orr was skeptical. “I just thought of those cheesy belt buckles from the 1970s and wondered if it would look gimmicky,” he recalls. But the San Francisco firm, known for its refined minimalism on such projects as the renovation and addition for artist David Ireland’s house, did use the color-changing material, to surprising effect, along with a freshly stripped-down material palette and updated lighting scheme, regenerating the nearly 40-year-old structure for the young screen-centric workplace.
