Apple on Wednesday announced that its long-awaited new headquarters, anchored by a 2.8 million square foot mothership building, is near completion. Named "Apple Park," the complex will make its official debut in April. The 175-acre campus, which falls somewhere between the Pentagon and an Olympic village in terms of size, is the fulfillment of the dream of Apple cofounder Steve Jobs. It will be the new home for more than 12,000 corporate employees. It will take about six months for staff to relocate to the campus.
