This paper analyzes development of the International Style architecture in the United States before 1932, especialy in the field of multistory building. The development, begining in 1926, can be divided into four phases. The first phase appers in some pioneer's projects. Four conditional characteristics of the International Style apper in this phase. In the second phase, a pseudoribbon window is used for emphasis on horizontality. In the third phase, a ribbon window supported by cantileverd floor slab makes strong horizontal sense. Finally in the fourth phase, elemental composition appers in some works.
