The purpose of this paper is to clarify how to give an effect to the living of the inhabitants of Imported Housing Villages, from the viewpoint of their opened streets, especially barrier-freed front yard. The results of research are as follows:
1. The opened front yard without gate and tall fence grows up “the consciousness of common community” at private and public buffer zone.
2. The opened front yard lets inhabitants arouse the relation of “see vs. seen”, and lets their living give stimuli such as house decoration, lawn trimming and play of children.
3. The opened front yard conserves living environments, activates communication between neighbors and builds up the community of good quality.

 In the current Japanese urban areas, bonds of local residents have been dilutive, under the influence of low birthrate, aging, personalization of life, and diversification of values. After Great Hanshin-Awaji Earthquake, these problems become obvious, and there has been a growing demand to regeneration of neighborhood community.
 The purpose of this study is to explore the way of planning of open type dwelling unit to activate the community. This paper examines the relationship between the dwelling unit plan and the formation of territory on 3-dimensional streets in case of the experimental housing "NEXT21". Especially, focusing the "Visual connection" between a living room and a 3-dimensional street, we analyzed the spread of personal areas on 3-dimensional streets.
 If there is a "Visual connection" between a living room and a 3-dimensional street, it caused the "intermediate space" with the device in the vicinity of the boundary. The device is the invitational design technique, also the exclusive design technique. Due to differences in the arrangement of the "intermediate space", they were classified into five types of "Visual connections" between a living room and a 3-dimensional street. To target the dwelling unit that has direct "Visual connection", we analyzed "Areas of comfortable" and "Areas to be worried about if there are strangers". "Areas of comfortable" are recognized as the private areas of proceeds. "Areas to be worried about if there are strangers" are recognized as the areas visible from the familiar life spaces.
 If the living room of the dwelling unit is spread in the "intermediate space", "Areas to be worried about if there are strangers" are formed in the areas of "Visual connection" with not only the living room but also the "intermediate space". Furthermore, "Areas of comfortable" are formed in the areas of the invitational quality. However, "intermediate space" having a large opening prevents the formation of "Areas of comfortable" under the influence of the exclusive quality.
 Through analysis, we were able to see how the private areas spread the living room to the "intermediate space" and 3-dimensional streets in stages. Simply not only to pursue the securing of privacy, but also it is necessary to perform open type dwelling planning in the hope that the community will be formed after a few years. There, it is important that "intermediate space"s become cores of communication, and connect in three dimensions by "Visual connections".
