"The Japanese society is quickly emerging into an aging society. It is estimated that in the year 2020, about a quarter of its population be those 65 and over. It necessitates newer policy developments of housing the aged persons because previous way of living as an extended family is losing its ground in the social system. "Silver-Housing' is one of the solutions to the problem of housing the aged persons. It is a form of special housing scheme for the aged, proposed by the Ministry of Construction which is in charge of housing supply in cooperation with the Ministry of Health and Welfare which is responsible for social services. Its basic concept comes from the sheltered housing scheme in the U.K. An in-depth survey of age-conscious design features of the silver-housing was conducted in order to critically examine their effectiveness. This is because no standard guidelines were available to design such schemes. Most of the references for design have been based on the recommendations of barrier-free design for wheel-chair users and it was clear that great gaps exist between two user groups, i.e. the elderly and the wheel-chair users. Five schemes were surveyed with detailed questionnaire form focusing on their special design considerations. Design features commonly adopted include: hand-rail installation; emergency response systems; and lever handles for doors. It was intended to find out problematic design mistakes for future references, as well as to know characteristics of aged residents in such special dwellings. It was hoped that physical characteristics of the aged be examined from practical point of view: to what extent they can live by themselves and to what extent they have to be cared for.The results of the survey suggest that: 1) The residents are much healthier than normally assumed. 2) They are enjoying their life in their "Silver-housing." 3) They already have minor troubles in and around their dwelling units. 4) Some design considerations are inadequate to the aged residents. 5) The warden, "Life support advisor," is experiencing trouble because their responsibilities are not well defined. 6) The lack of integrated social services seems to accelerate complaints among residents. If similar physical design features are introduced to ordinary dwellings, they will surely support aged persons, even without resident "Life support adviser."
