Abstract
This study is purposed to analyze the changes of domestic spaces for modern nuclear family in comtemporary situations through SANAA's works. Regarding composition of rooms, SANAA's works tried to make a new relationship between common spaces and individuals' spaces at their early works, however, their later works showed non hierarchial composition of independent rooms. These rooms also were tried to be redefined in the aspect of uses and spatial concepts instead of conventional nLDK systems. Moreover, those compositions amplified the distinctive perceptual experiences in the relationship between a residence and a city, or a room and another room. Those experiences are based on complexity revealing feeling of privacy within boundary and connectivity to another space at the same time. SANAA's domestic spaces can be one of strategies for contemporary family spaces showing individualization of family members and ideological family togetherness at the same time.
