As the advent of an aging society, housing for the elderly has been of greater concern. Since the majority of the elderly prefers to live in their own familiar houses rather than moving to new ones, this study is concerned with the ways of the effective use and maintenance of exiting houses from the viewpoint of their independent living. The data was analyzed with frequency, percentage, mean, correlation, and multiple regression using the SPSS 10.0 for Windows. The findings from the study are: The general satisfaction rate of Interior Design Affordance(IDA) was-evaluated about the average. Among the items of IDA, behavioral facilitation was found most satisfactory, and perceptual maintenance, physilogical maintenance, and social facilitation were followed in satisfaction level. Although there had been many elements of serious safety dangers, no home modification was made in the elderly households who live alone or/with spouse.
