Residential site should have pedestrian road passing through the center of the site just for convenience and safety. However, apartment complexes developed in the past, the sites are just stuck by walls and pedestrian roads are not placed, inhabitans have difficulties for facility use and safety. Therefore, residents solve the problems as follows: they utilize the spaces, between apartment building and the wall, as walking route, and demolish the parts of the wall for connecting sites. In this study, it was thought that pedestrian road could be emplaced at the wall space between sites. For this, a low-rise apartment complex in Gwangju was selected developed in 1990s, and whether the space for pedestrian road was examined. The width from 2.4m to 8.0m could be secured, and there could be placed the pedestrian road at the wall space. However, this study is limited for the possibility of securing space, for the opinion of residents that might be damaged from the pedestrian road did not reviewed.
