The Johnson Wax Headquarters were in an industrial zone, and Wright decided to create a sealed environment lit from above, as he had done with the Larkin Administration Building. The building features Wright's interpretation of the streamlined Art Moderne style popular in the 1930s. In a break with his earlier Prairie School structures, the building features many curvilinear forms and required over 200 different curved "Cherokee red" bricks to create the sweeping curves of the interior and exterior. The mortar between the bricks is raked in traditional Wright style to accentuate the horizontality of the building. The warm, reddish hue of the bricks was used in the polished concrete floor slab as well; the white stone trim and white dendriform (tree-like) columns create a subtle yet striking contrast. All of the furniture, manufactured by Steelcase, was designed for the building by Wright and it echoed many of the building's design features.
