The S.C. Johnson Headquarters in Racine, Wisconsin, designed by Frank Lloyd Wright in the 1930's occupies an important place in architectural history. It is one of my favorite designs by America's most famous and perhaps greatest architect.
The Administration Building, the first building designed by Wright and built in 1936 which feature the famous “mushroom” columns. The Research Tower opened in 1950, where such products as RAID™ and OFF™ were invented; The Fortaleza Hall includes an 888-square-foot vertical garden and, at its center, the replica Sikorsky aircraft flown by Sam Johnson and his sons to Fortaleza, Brazil; and The Golden Rondelle originally built as the SC Johnson Pavilion at the New York World’s Fair in 1964-65, which is now the entry to the campus.
Each of these buildings have unique features. The Administration Building and carport has columns with huge mushroom capital and were controversial and of a design far ahead of the times.
Also, most interesting is that the Research Tower has no glass windows. The exterior walls between floors are made of Corning Pyrex™ glass tubing. The interior is flooded with light but impossible to see through, inside or out.
Fortaleza Hall has a beautiful world map made of different species wood inlaid in the marble floor. The Sikorsky aircraft is suspended overhead from the roof structure.
