The architect referred to the traditional Nambu Magariya houses of the Tohoku region, which have an earthen floor (doma) as the central feature of the living space. The design places the earthen floor in a cross-shaped layout, with the kitchen, living room, Japanese-style room, and upstairs bedrooms all adjoining it. Each room connects to the earthen floor, creating a continuous space with various openings of different sizes.

The building envelope includes skylights and large openings, forming multiple layers of boundaries between the interior and exterior, in conjunction with the openings on the mezzanine side. The architecture takes on a large cross-shaped form, positioned at the center of the rectangular site, creating four distinct gardens. This layout fosters a living environment with diverse relationships to the surrounding external environment.
