The Boeing Everett Factory, in Everett, Washington, is an airplane assembly building owned by Boeing. Located on the north-east corner of Paine Field, it is the largest building in the world by volume at 13,385,378 m3 (472,370,319 cu ft) and covers 399,480 m2 (98.7 acres; 39.948 hectares; 0.399 square kilometres).
This is the factory where the wide-body Boeing 747, 767, 777, and 787 are assembled.
Plans for the factory were first announced in 1966 for it to be the site of the construction of the 747 after Boeing was awarded a contract worth US$525 million (equivalent to $4137 million in 2019) from Pan American World Airways to build 25 747s. It purchased 780 acres (320 ha) north of the then little-used Paine Field.
The factory includes a Boeing Employees' Credit Union branch and several cafés. Across the airport to the west is The Boeing Store, a theater, and a Future of Flight Aviation Center, which runs the factory tour. The Boeing Everett campus is big enough to encompass The Magic Kingdom in Disneyland with 12 acres (4.9 ha) left over for parking.
The Everett Factory currently employs over 30,000 people, including its own fire department, security team, daycare center, coffee shop, and fitness center.
