In this paper, we used three kinds of variable with duality to make experimental environment and to reveal the physical dimensions of the ideal dwelling environment : detached/collective housing, the presence/absence of a macro concavity (enclosure) formed from the natural topography of mountains, and the presence/absence of a micro concavity formed from the arrangement of houses. We were able to confirm that the housing style and two types of concavity (visualized in the housing arrangement forms and the presence of mountains) were promising as dimensions of the ideal dwelling environment.
