A main house and a detached house are built on a deformed site where two lots are connected back to back, and they are connected by a large roof. The large roof rises in the center to maximize the solar radiation in winter. Air taken in through the eaves of the roof is supplied to the top light section, heated, and stored in the heat storage layer on the foundation through the central steel pillar.
