Apple Campus 2, Corporate Headquarters Of Apple Inc., Cupertino, California, United States

Original campus
The Apple Campus is located on the southeast corner of Interstate 280 and De Anza Boulevard, and occupies 32 acres (130,000 m2) in six buildings spread over four floors. Each building is numbered with one digit on the private U-shaped street Infinite Loop, so named because of the programming concept of an infinite loop. The street, in conjunction with Mariani Avenue, actually does form a circuit (or cycle) that can circulate indefinitely. The main building has the address 1 Infinite Loop, Cupertino, California. Employees refer to these buildings as IL1 to IL6 for Infinite Loop 1-6. Besides the buildings on Infinite Loop, the whole Apple Campus occupies an additional thirty buildings scattered throughout the city to accommodate its employees. Some of these buildings are leased (with an average rental cost of USD $2.5 per square foot), while others are of recent acquisition; the land the new buildings occupy will be used for future construction of a second campus in the city with the aim of centralizing the activities of the company. In total, including nine newly acquired buildings on Pruneridge Avenue, the company controls more than 3,300,000 square feet (310,000 m2) for its activities in the city of Cupertino. This represents almost 40% of the 8,800,000 square feet (820,000 m2) of office space and facilities for research and development available in the city.
