This care facility in Saitama, in the sub- urbs of Tokyo, is for elderly people capa- ble of living alone and provides support such as dining, bathing and health man- agement facilities. Private rooms are locat- ed in the center of the site, dividing it into two parts. The parts are further divided by the administration, dining and bathing blocks, leaving space for a number of gar- dens, each with a distinct character.

The internal spaces connect the gardens, pre- venting them from being isolated, and maintain the unity of the site. As a result of this, the interior does not need artificial lighting during the day. To provide com- fort for the elderly, spaces allocated to the residents have been made as large as pos- sible by minimizing the width of the corridors, while still allowing for wheelchair access. The slit windows in the north wall were designed using the Fibonacci series.
