In Jiyugaoka, a residential area is located at the top of the hill, and an elderly care facility and a school are located next to each other at the bottom. However, there is no interaction between these two facilities, and the elderly care facility is closed. Therefore, in order to allow children to enter the facility, a section of the building was manipulated and three plazas were created in plan. In this way, interaction between the elderly, school children, and local residents is created, and the elderly, who used to only receive care, are now actively involved.
