Abstract: During early days of architecture, Le Corbusier tested Dom-Ino system which imply the possibility of reinforced concrete. In the late period, different from what Le Corbrusier experiment, architecture was focused on form and material that was based on regionalism, primitivism, brutalism and etc. In this thesis Housing 4 composition and Villa Jaoul (Villa Neuille-sur-Seine) have been compared and researched which both represent early and late days of architecture to look underlying theme and overall thinking process of Le Corbusier.The result of this study is as follows: space where it is surrounded by geometric arrangements and architectural elements arouse the inspiration and choose of traffic line. it shares transparency and also inherits the expandability of Dom-Ino system; As a characteristic of interior and exterior of architecture, exchange and share different elements by open boundary, abstractness of the wall forms the relationship with the nature outdoor. Trail of architecture is a overall memories of architectural elements and this trail will reach to soft and cozy place. As conversational tone is added to the followings above, it will remove the massing but increase the optical illusion and motion. Le Corbusier's architecture differ in structural method and possibility of reinforced concrete but still maintained the context of characteristics of space and technique.
