What type of office design is best for productivity and engagement? Today, this common question tends to have two distinct answers. On the one hand are the tech start-ups, who advocate for open office plans that emphasize chance encounters. Google’s new campus is designed to maximize chance encounters, and Facebook’s new headquarters features the largest open office in the world. Samsung is also exploring the use of more outdoor space to encourage employee conversation. As Scott Birnbaum, vice president of Samsung, told HBR, “The most creative ideas aren’t going to come while sitting in front of your monitor.” Their new building “is really designed to spark not just collaboration but that innovation you see when people collide.”
