The John Deere World Headquarters (or John Deere Administration Center) is the corporate headquarters for the agricultural equipment company John Deere (also known as Deere & Co.) in Moline, Illinois, United States. The complex consists of four structures, three of which are interconnected. Eero Saarinen designed the original two structures, namely the main and display buildings. Roche-Dinkeloo, a firm founded by Saarinen's former associates Kevin Roche and John Dinkeloo, designed the Deere West office building next to the main building, along with the Financial Services Building on another part of the site. The landscape, designed by Sasaki Associates, includes two lakes.
The main building, display building, and Deere West are clad with Cor-Ten weathering steel and glass. The seven-story main building is located in a ravine and is accessed by footbridges on its fourth floor, which lead east to the display building and west to Deere West. The main building and Deere West both function as office structures; the offices in Deere West are arranged around a garden atrium with glass roofs. The display building contains an auditorium with two levels, along with a display area with a sculpture mural by Alexander Girard. The John Deere Headquarters received a large amount of attention from architectural critics when it was completed. It has also received numerous awards, including the Twenty-five Year Award for architectural excellence.
