Mies searched for architectural 'order' in his life-time. He told that there were different stages of 'order,' from a practical order to a spiritual one, according to a hierarchy of values. In Crown Hall possessing the highest value Mies took the grid in a larger measure than the 24 feet grid. The analysis of Crown Hall and the other buildings on the IIT campus derived that a spiritual order was realized by not only a larger measure but also golden proportion. It reveals that the golden proportions in his works related to his architectural idea, 'order.'
