1. Group-Living as a Home for People with Dementia from Long-term Point of View Satoshi ISHII* and Shuang YAN *Dept. of Architecture Tohoku Institute of Technology Sendai, JAPAN

2. Group-living for people with dementia in JAPAN • Group living … • Small collective residential facilities • Homelike atmosphere and high quality of care • Alternative form to the traditional institutions • Increasing from mid of 1990s • Over 5,000 places in Japan and 45,000 people living • Regulated as a place for dementia with 5 to 9 residents

3.

16. LONGITUDINAL and CONTINUOUS SURVEY • Considering into changing factors • Importance of axis of time Fig. Survey Date, Changes of People and Their Conditions

17. It is not uniform and stable Date of Survey Fig. SPACE USAGE The Rate of the Space Usage in Each Survey Period

20. Stay alone but feel others and activities Positive stay with a few friends with Gathering guided or for programmed activities

21. Pattern of Staying in Common Spaces Viewpoint from Dementia Stage

22. Date of Survey Pattern of Staying in Common Spaces Viewpoint from Dementia Stage: Individual case 1

23. Date of Survey Pattern of Staying in Common Spaces Viewpoint from Dementia Stage: Individual case 2

24. RESULTS (1)Space usage is not uniform and stable. (2)Several factors bring changes of living. (3)Longitudinal and continuous survey can cover the changes and tell the life of group living and dementia.

25. People with dementia need support for their life. Architectural environment is to be one of them. Carefully designed architectural environment made it possible to correspond to each resident’s pattern of life and the changing. Longitudinal survey is very useful to show the various patterns of living and the changing, and understanding of place for dementia.
