I worked at Apple during the years when the company designed and built its first campus at 1 Infinite Loop in Cupertino. As I recall, Apple R&D employees were considered stakeholders and participated in the design of the interior spaces. Apple wisely decided to give each engineer a private office. There were open areas near the offices with comfortable furniture and whiteboards for engineers to meet and collaborate. I worked in one of these buildings from 2001-2007, and I can confirm that the work areas were beautifully designed and ideal for fostering productive work. It's sad to hear that Apple apparently abandoned this approach in its new campus.
