The Dodge Factory, or "Dodge Main" as it became known, occupied on the edge of the village of Hamtramck, which is surrounded by the city of Detroit. Plant 4, on Conant Avenue, was separated only from the main plant structures by a railroad right-of-way, which was also the boundary line between the two cities. The plant started off as just a few buildings but it grew rapidly as needed, where it ended up as 35 separate buildings, to include a foundry, before it was demolished. The original plant was designed by noted industrial designer and architect Albert Kahn Associates but were replaced in 1912 by the architectural firm of Smith, Hinchman & Grylls, due to a disagreement with the Dodge brothers. Reflecting an engineering philosophy the brothers shared, the plant was vastly overbuilt.
