The main idea for design is taking facade as clothes when architecture was human being. Facade as the skin of building could be transformed into architectural clothes for flexible change according to the different situations. When modern architecture presented the simplicity of geometry as the trendency in modern society, when box-architectures were abandoned, left there, lacked the attentions, when people were bored about the building they lived in, is there any possibility can reuse the old building, renew the architecture in easy and cost-efficient way? In the basis of mathematics in geometry, programming and the method of origami, I try to redesign the facade of Crown Hall designed by Mies van der Rohe, subdivid them into panel, which as one unit for redecorating the facade of building in terms of user needs.
