The approach is a square concrete entry court that echoes the form of the building.
A simple house form: a true 8.1 m × 8.1 m square plan under a pyramidal hip roof.
Entrance leading to the doma; the floor is mortar tinted with sumi ink.
A door fitted with antique glass panels serves as the entrance to the living room.
Doma-style garage. Beneath the mezzanine is a secret hideout.

Sakai City, Osaka Prefecture. A residence sited on the mid-slope of a gentle hill left behind by new‑town development. We established a single, large house‑shaped volume with a square plan measuring 8.1 m on each side, and by inserting four small houses that emanate from each corner within it a cruciform void is produced between the small houses. Because each small house assumes a different internal volume according to its functional requirements, the gaps become not clean intersections but distorted spaces akin to the four corners of a back alley. The small houses and these corner spaces are connected by incised apertures; they invert and, alternately opening and closing, nurture the inhabitants' daily life. The exterior is conceived as an abstract house‑shaped icon clad in the tactile texture of yakisugi (charred cedar), while the interior, despite a complex skip‑floor spatial arrangement, is composed as a simple white cube. By balancing these opposing conditions, we conceived a dwelling appropriate to this site where the new town and the old village press against one another and age together, approaching a certain equilibrium.
