 Typically, older buildings up to 1956 had columns to support the roof from caving in, but Crown Hall does not require them.While designing Crown Hall, Mies stayed true to his famous words, "less is more" and he considered the building to be the best embodiment of the maxim.At the time of being built, the idea of providing a single large room for the school of architecture and city planning's 300 students was to be particularly workable, and for the student to not be isolated from others who may be further or less advanced in the course then he/she.
