Among all 121 houses in one building in Takashimadaira Complex, 30 houses dispersed on each floor were repaired as serviced elderly housing From the 2DK which was created with the assumption of a nuclear family 40 years ago, it was renovated into a living place where elderly people can live comfortably and securely. We held a workshop and made progress while talking with residents and local residents about what kind of residence to make. Sometimes I visited the residents' residence to conduct surveys on living conditions and made reference to the designs such as daily flow lines, the movement around the water and the entrance. It is a project that becomes a model of stock utilization in the first attempt to improve the residence distributed in the residence as serviced elderly housing.
