Question

Louis Sullivan designed skyscrapers with three functions, or sections. What was the second section used for?

Answer 1

Louis Henry Sullivan outlined his skyscraper theory six years later in his most famous essay, 'The Tall Office Building Artistically Considered". By carefully analyzing the program requirements, Louis Henry Sullivan decided that skyscrapers had three major clusters of functions, each of which should be expressed separately. The first was public-seen on the one-or two-story base-consisting of entering and leaving, meeting and greeting, waiting, shopping, and locating the entrance from the outside. The second set offunctions was private: various kinds of office work. And the third was architectural: the housing of mechanical equipment and storage in an attic that could also serve as an aesthetic device for terminating the facade in a decisive way.
