Facebook's sprawling 200-acre headquarters campus in Menlo Park, California, reflects the company's creative values and global prominence as it turns 15 years old in 2019. Its amenity-laden atmosphere is aimed at making the offices a home away from home for as many as half of its 33,000 worldwide employees when the campus completes its planned expansion to 4 million square feet. From vending machines that dispense phone chargers to artistic murals along major corridors, the campus was designed with an emphasis on connectivity and creativity while removing barriers to employee productivity.
