Facebook is on the move...literally. In relocating its headquarters campus, the company recently redesigned and retrofitted the former Sun Microsystems campus in Menlo Park, Calif., to LEED Gold standard while also integrating attributes of its own culture into the retrofit. New open office spaces reflect Facebook's ways: flexible, comfortable and social. The company greatly values its employees' comfort in and preferences for their work spaces. It sees its built environment as a prominent contributor to their productivity.
