This study aims to clarify the overlapping between inside and outside generated by the arrangement of linear elements in published contemporary Japanese urban houses designed by architects after 1970. In the high-density urban environment, the overlapping has the potential to transcend the physical boundaries and generate the externality. Initially, the externalized internal area (Ae) and the area of linear elements (Al) were defined. Next, the spatial composition of overlapping and boundary characteristics were clarified. Then, 13 types of overlapping with different independence were summarized. Finally, the relationship between the independence of each type and the chronological distribution was concluded.
