The aim of this study was to make clear the aspect of the double structure in the use spheres of assembly facilities for community and the efficiency of the double facility distribution system. The findings of this study were as follows. The use spheres of assembly facilities for community expand over the school districts which are planned as the use spheres for those facilities. Especially there is remarkable expansion at the facilities in the midtown area, the sub-center district and the urban-type housing area.
