The aim of this study is to clarify the rhetoric of composition on open bedrooms in Japanese contemporary houses. Continuity of spaces including open bedrooms is more complex because of the necessity of privacy and time-sharing. Thus new relationships emerge from the conflict of spatial continuity within private space. In this study, the compositional characters of open bedrooms are analyzed in terms of certain components: articulation, transparency, circulation, and relation to architectural elements. As a result, compositional patterns are defined by the combination of these components of the open bedrooms. Finally, the rhetoric of composition is revealed from overlapping of programmatic distinction and spatial contrast in the continuity of the common and bedroom areas.
