When Slack asked O+A to create a new multi-floor HQ in San Francisco one design story presented itself immediately. Slack’s team saw a value in having each floor reflect the variety and irregularity of nature. One of their goals for the space was that it generate the cooperative spirit and resourcefulness hikers experience on a wilderness trail. O+A’s solution was to create a floor-by-floor evocation of the landscapes that make up the Pacific Crest Trail—desert, mountains, forest—in effect to turn a trip up the elevator into a virtual trip from Baja to the Pacific Northwest.
