This study examined the awareness of the middle aged about the digital home system and well-being apartment design elements in order to suggest the design guidelines for planning of the elderly housing environment. By literature review, the concept and characteristics of the digital home system and well-being Apartment design elements were summarized the degree of satisfaction and preference of middle aged for these characteristics were investigated and analyzed. For this study, a questionnaire survey of 156 housewives living in apartment complex of Busan was carried out. The results of this study are as follows: The middle aged were generally short of recognition for digital skill and service, and also they showed positive evaluations to a few useful items of digital home system. These items belong under safety security system and interior environment control system and provided for convenient & comfortable life. Accordingly, satisfied digital home system can apply basic design element for housing for elderly. Whereas, the middle-aged were not satisfied with housework help system and cultural life system because items of these systems were not various and complicate to us. So, for the improvement of not satisfied digital home system, we needed development of digital contents and marketing & management for high accessibility and easy useability. The middle aged will concern about health & environment friendly continuously and become to stay long in their housing as the characteristics of elderly. So, It is necessary to be considered well-being apartment design elements of health & environment friendly very actively and lastingly in elderly housing environment design. Also, the awareness of middle aged for digital home system and well-being apartment design elements varied according to the background characteristics. This suggests housing environment for elderly life is considered differently as various background characteristics of middle aged.
