In response to a growing company's request for office space, Kevin Roche John Dinkeloo and Associates developed a master plan that would allow the incremental addition of floor space over time. The initial design included nine identical buildings arranged in a parallelogram, totaling 1.2 million square feet. Only three of the buildings were constructed in the initial phase, and the expansion plan was never fulfilled. The trio is known as "The Pyramids" for their simple geometry and slanting glass facades.
Kevin Roche and John Dinkeloo established their own practice in 1966, after heading the firm of Eero Saarinen for several years. The Ford Foundation Headquarters is regarded as the pair's first major success, a combination of Roche's unique ideals and Dinkeloo's innovative structural solutions. They introduced an office typology in which employee interaction extended beyond departments and levels, reaching even to the public.
