This paper aims to analyze the characteristics of the spatial system of basic settlement areas, to identify spatial problems, and propose appropriate management and strategies for detached housing areas. For the urban settings of basic settlement areas, land use, buildings, circulation, urban facilities are explored. The key findings of this study are as follows; 1) the lack of small neighborhood-scaled infrastructure causes the fall and deterioration of detached housing areas and cannot serve residents’ comfortable life. 2) vehicle-pedestrian mixed street and street parking system are negatively associated with pedestrian safety and can contribute to traffic congestion. Pedestrian-oriented circulation and more public parking space are needed for pedestrian safety. Finally, the recent plan for neighborhood-based settlement is not appropriate for the detached housing area plan. This paper suggests the need to identify the spatial scope of basic settlement areas based on the accessible distance from children parks, and to build the criteria and interventions for basic settlement in order to provide proper urban facilities.
