In our modern society, everything is shrinking, including office space. In the 1970's, office space averaged about 500-700 square feet, today those numbers are around 200 square feet per employee. Companies such as Zappos only allocate 150 square feet to each employee.
Some companies find ways to use their real estate even more efficiently by creating flexible workstations. Alcatel-Lucent, for example, accommodates 450 employees at 250 workstations and Credit Suisse uses 2000 workstations for 2500 employees.
