Rapt Studio has designed the new headquarters of virtual storage company Dropbox, located in San Francisco, California.

The magic of Dropbox is it allows you to work anywhere, using a nearly invisible interface. But the company’s 300,000-square-foot physical offices couldn’t be invisible. The space needed deliberate visual cues to support collaboration among the company’s many teams.

The solution: a bustling city layout based on landmarks, neighborhoods, and shared community values.
