Abstract The purpose of this study is to identify the importance of physical environmental factors in public spaces of public rental housing and provide design planning data to improve the living safety of public spaces. The subjects of the study are researchers and public officials related to apartment planning and housing welfare, and architects with design experience. The factors to be considered first and the importance of physical environmental factors for each public spaces were analyzed. For the research method, Delphi method and AHP analysis method were used for apartment housing experts. The research results are as follows. In the first expert opinion survey, safety was an important planning concept in pedestrian, playgrounds, sport facilities, ground parking ares, bicycle parking ares, elevator halls, inside of elevators, and stairs. In the second survey, the ranking of the physical environmental factors related to living safety appeared in the order of lighting, color, finishing materials, and landscaping. The priorities of researchers and public officials were lighting, sign color, finishing materials, and landscaping, while architects were in the order of finishing materials, sign color, lighting and landscaping. Public spaces for which lighting is important are the main entrance of the complexes, above-ground parking ares, pedestrian, playground, entrance to residential buildings, underground parking ares, inside of elevators, stairs, and corridor. The spaces where sign color is important are the main entrance of the complex, the playground, the entrance to residential buildings, and the underground parking ares. The spaces where the finishing materials are important were pedestrian, playgrounds, rest facilities, sports facilities, and the inside of the elevator. As for the importance of lighting, the importance of sign color in the playground showed a significant difference between the groups in the elevator hall and inside of elevator. The importance of finishing materials was found to be significantly different at the main entrance to complexes, rest facilities, mailboxes, and elevator hall, and the importance of landscaping showed significant differences between groups at the main entrance to complexes and playground.
