Design Summary

This project is a welfare facility designed to care for the elderly. The design is like Japanese traditional porch "Engawa" where locals can drop in casually. It's also a community base for welfare that is a place for the elderly, children, and locals to help each other in times of trouble.

Key design points

  • A day service facility that is not dependent on the system, but a community-based day service facility that fosters mutual support and coexistence among local society and individuals.
  • The facility is designed as an architectural embodiment of a small town, with a café, a temple lodging, a day service, and a public bath, where the place open to everyone.
  • The Engawa that connects the facilities to the community with various accesses. The Engawa where everyone can spend time together. The Engawa for each individual to have a good time.

Jury’s Evaluations

It is a place where people can help each other in the community. It’s unconventional day-care service. It’s operated as a day-care facility, but welcomes everyone from babies to the elderly, which is so wonderful. Perhaps there are supporters who agree with the community vision and a support system where people can help each other. The elderly are not only supported, but watch over children. Children help the adults. Everyone helps each other. It reminds us of old times. The long engawa-style deck and wide space under the roof embody the concept beautifully and cause the actual situation. It seems that he has conducted workshops on garden building and has been working hard to create a place of trust. Its steady approach is also highly commendable.

Good Design Award winners' comments

In an age when efficiency and convenience are demanded in various aspects, we created this facility because we believe that the elderly need a place where they can live with dignity as human beings. We believe that the happiness for those elderly often comes from daily communication with children and people of various generations. Through this facility, we are hoping to bring back the views of a society where not only the elderly but also everyone can live happily by communicating with each other which are being lost in today's society.

Japan is experiencing a rapid aging process unparalleled in other countries. The population of individuals aged 65 and over now exceeding 35 million and expected to peak in 2042 at about 39 million. Furthermore, the percentage of the population aged 75 and over is expected to continue increasing.

Under these circumstances, the demand for medical care and long-term care services is expected to further increase after 2025, when the baby-boom generation will reach 75 years of age or older. Therefore, the Ministry of Health, Labour and Welfare (MHLW) is promoting the establishment of a comprehensive regional support and service system for local communities (the Community-based Integrated Care System) with the goal of preserving the dignity and supporting independent living for the elderly. This system aims to enable individuals to continue living in their familiar communities and lead a life true to themselves until the end of their days, with a target of around 2025.
