Quad 7 Hangar, Boeing Field

Status: Demolished

Year Listed: 2010

Constructed in 1962 for West Coast Airlines, the hangar was designed by John Morse of Bassetti & Morse, a prominent architecture firm in the Pacific Northwest during the mid-twentieth century. The structure also represents the work of Skilling, Helle, Christiansen and Robertson, an engineering firm whose principal, Jack Christiansen, is best known for his work on thinshell concrete structures and was considered a world leader in their design. Demolition is planned by the current tenant who leases the property from King County and uses it to service and outfit small jets and planes catering primarily to corporate clients. Re-development plans for the site include construction of seven new hangars.
