As one of the earliest adopters of the Designers Accord, Portland-based Ziba Design has long anchored the sustainable design industry in the Northwest, and have since expanded to San Diego, Tokyo and Shanghai. But as the firm’s headquarters grew in numbers–100 this year–they also outgrew their space, both physically and organizationally. Several years ago they tapped local architects Holst Architecture to begin collaborating on a building that was not only LEED-certified, but one that better served the local community, where Ziba first laid down its roots over a decade ago.
