The aim of this study is to clarify the conditions of architectural planning for high-rise housing where the aged keep living in. This is based on the results of two questionnaires - investigated in 1989 and 1999 - given to the aged who keep living in high-rise housing over 10 years. And then, we find changes of their attribute, intention of settlement and their housing preference to housing style where they live in. First, we can clarify changes of family-type and working which happen to half of them. And then, we find they are getting more intention of settlement. Finally, we were able to clarify the relation between changes of their housing preference and building types, dwelling floors.
