The Boeing Everett Factory in Washington, USA, is the largest building in the world in terms of volume. The building, used for airplane assembly, covers 399,480 m2 (98.3 acres) of land whilst taking up 13,385,378 m3 (472,370,319 cu ft) of space. Owned by Boeing, the factory was originally built in 1967 with the intention of manufacturing the Boeing 747, but has since expanded to also produce the 767, 777 and 787 airplanes. It has become somewhat of a tourist attraction with thousands of visitors a year, including the likes of U.S. presidents and astronauts.
