Hughes Aircraft Company, Manufacturing Building, 6775 Centinela Avenue, Los Angeles, Los Angeles County, CA

Significance: Conceived as a research and development building for the Guided Missile Department, Building 20 is a rectangular, high bay single story, steel frame post and beam structure with an L-shaped one story concrete block addition at the southeast corner. ... The 78,000 sq ft building initially housed more than 500 personnel of the Guided Missile Production Planning and Engineering Department. Original plans indicate that a large open shop area occupied most of the north half of the building, with an open general office area ringed by small offices and support rooms in the three easternmost bays. The south half of the building, west of the offices, contained smaller, specialized shops and laboratories with areas for shipping and receiving, assembly, testing and inspection, processing, and jig production. The central corridor did not exist and circulation to these spaces was by way of a U-shaped corridor accessed from the main shop area.
