Tato Architects completes house in Mibu

A residential structure in Japan utilizes charred timber and sunken levels to balance enclosure and openness.

Local studio Tato Architects has finished House in Mibu, a residence located in Tochigi Prefecture, Japan. The building features charred-timber cladding on its exterior, which contrasts with interiors lined in warm plywood. The home was designed for a couple and their three children. It sits in the backyard of the client’s parental home, positioned off a residential street in the town of Mibu.

The site presented specific logistical requirements. It needed to accommodate access to an existing garage and workshop. Kobe-based Tato Architects aimed to balance enclosure and openness in its design response. The final layout reflects this objective through its physical form. The first floor overhangs on one side. The ground floor is sunk 500 millimetres below ground level. It is partially topped with a sloped green roof.

Studio founder Yo Shimada described the core concept as the in-between. He referenced Dutch architect Aldo Van Eyck, defining this realm as one where enclosure and openness are experienced simultaneously. The challenge involved adding a whole house without making the yard feel crowded or cutting off the life already flowing through it. Rather than treating these constraints as obstacles, the studio allowed them to shape the building. Shimada explained that sinking the living room into the ground and planting its roof with grass creates a single operation where sinking into the earth encloses and touching the earth opens.

Entry to the house occurs beneath the overhang of the first floor. A welcome area with a cloakroom and bathroom steps down into a sunken living, dining, and kitchen area. Full-height windows wrap this lower space to the west. This design choice aims to emphasize the close relationship to the ground while offering views into the neighbouring workshop.

A pair of timber and green-painted steel staircases lead up through a rectilinear void to the home's first floor. The bedrooms are organized on either side of a raised, loft-like space. This upper area can serve as a study or guest room. The lines of sight created by these stepped levels define the home's interiors. Walls and ceilings are lined entirely in lauan plywood. Shimada chose this material for its ability to record use and age gracefully. Sitting in the living room, the ground of the garden spreads out almost at eye level. Family members working in the yard and those inside exchange glances across a slight shift in height. The first floor acts as a counterpart, described as a nest-like composition of small rooms. These include three children's rooms and a bedroom, linked by two staircases. A loft is raised 690 millimetres above the main level of the first floor.

Takeaway: The total floor area of the completed residence is 108 square metres.
