With mobile devices invading the workplace and more workers telecommuting, many companies—and the design firms that serve them—are rapidly changing their thinking about conventional office space.

Cubicles are passé; flexible spaces that allow employees to log in, collaborate, and hit the road are all the rage. The goal is to support the mobile workforce, increase the opportunities to interact, and save money by using space more efficiently.

This design trend is partly a response to events: cubicles are already emptying. An internal study by Cisco, for example, found that cubicles at the company’s office were vacant 35 percent of the time because workers were telecommuting or working elsewhere on the company’s campus.
