The Packard plant on East Grand Boulevard in Detroit was located on over of land. Designed by Albert Kahn Associates, it included an early use of reinforced concrete for an automotive factory when building #10 opened in 1911. Its skilled craftsmen practiced over 80 trades. The dilapidated plant still stands, despite repeated fires. The factory is in close proximity to the current General Motors Detroit/Hamtramck Assembly, which was the former site of the Dodge Vehicle factory from 1910 until 1980. Architect Kahn also designed the Packard Proving Grounds in Shelby Township, Michigan.
