Jack Dorsey, the founder of Square, the mobile payments start-up, is a stickler for clean design. In the early days at the company, Dorsey was known to mandate employees clear their desks of clutter completely at the end of each day. Hence, the crisp, modern lines built into the company's new San Francisco headquarters--including these creative cubbies. Denise Cherry, the lead designer on the project, was most proud of what she calls the "tertiary spaces" built with plywood and felt.
