A mezzanine-floored residence consisting of a single-roomed space, located on a fan-shaped site.

The movements of the sun can be felt inside the house all throughout the year. Light coming from the east strikes the louvered boards before entering the house and reaching deep into its interior.

Direct sunlight from the south traces a shower-like path of lines as it penetrates into the building. Light coming from the west reflects off the walls of this house with an open stairwell before entering it.
