This hangar, located on the northwest end of Boeing Field, paid $3.4 million in rent to the landlord, King County, between 2002-2007. This figure was expected to rise to $7.3 million in 07/2007.

This enormous hangar, an immense half-cylinder of thin shell concrete, was the work of the innovative Seattle structural engineer, Jack Christiansen (b. 1927). Rainer Metzger, in his article, "Jack Christiansen Thin Shell Concrete in the Pacific Northwest," noted of the Boeing Field Hangar: "In 1956, Christiansen designed an eight-place B-52 hangar at Larsen Air Force Base in Moses Lake, Washington. The structure measured 376 feet by 1068 feet, incorporating 3-inch barrel vaulted roofs spanning an amazing 220 feet across each airplane bay. Another hangar project at Boeing Field in Seattle (1962) spanned even farther, 240 feet, by employing doubly curving, hyperbolic paraboloids, Here, segmented three-inch thick concrete shells curve in two directions. Sheltering these vast stretched of space with just a few inches of concrete creates a paradoxical sense of minimalism." (See Rainer Metzger, "Jack Christiansen Thin Shell Concrete in the Pacific Northwest," Column 5, vol. XX, p.9.)
