Site overview
In 1903, at the behest of a group of investors, the Packard Automotive Company moved its headquarters from Warren, Ohio to Detroit. Then-president of the company, Henry Joy, looking for a fresh take on factory buildings, enlisted local architect Albert Kahn to design the company's complex. The first nine buildings on the site were built between 1903-1905. These followed the typical mill-style factory buildings of the time, with cramped rooms, wooden columns, floors, and ceilings, and very little natural light. Due to the large amount of wood used in construction, these buildings were fire hazards. By the tenth building, Packard #10, Kahn wanted to improve the design, by providing open spaces and large windows for lighting and ventilation, making workers comfortable and more productive. To create this new style, he sought help from his brother, Julius Kahn, a well-known engineer who was experimenting with new ways to reinforce concrete. In 1904, Julius Kahn designed a trussed concrete steel re-bar reinforcement system, known as The Kahn Bar. This system features wings, bent at a 45 degree angle, along the length of steel re-bar which strengthened the concrete to prevent shearing at weak points. This design allowed for much larger loads to be carried on concrete, larger spans between support columns, and increased use of fire-safe materials. Utilizing his brother's Kahn Bar and the technical advantages it gave, Albert Kahn designed Packard #10 to be built using only reinforced concrete, allowing for the large open spaces and floor-to-ceiling windows that he wanted to provide for workers, along with much safer working conditions. The design for Packard #10 changed the way industrial buildings were designed and built. It was the first industrial building to use reinforced concrete for floors, ceilings, and columns. Through Albert Kahn's design for Packard #10, a new material and design concept were combined which changed the face of industrial buildings.
