House in Shikenbaru by Studio Cochi Architects – A Sustainable Farmhouse Integrating Okinawan Traditions

A Home Rooted in the Land and Climate of Okinawa

The House in Shikenbaru, designed by Studio Cochi Architects, is more than a family home—it is a living, breathing part of the agricultural lifestyle of its owners. Situated in a quiet village near the sea in southern Okinawa, the residence is designed for a couple and their four children, harmonizing with both the rural landscape and the rhythms of farm life.

Okinawa’s warm climate, free from frost and snow, allows vegetables typically grown in spring or summer on Japan’s main island of Honshu to be harvested year-round. This unique agricultural context directly shaped the architectural concept.

Living in Sync with Farming Rhythms

The homeowner runs a local farm, cultivating okra, green beans, papaya, and other crops. His workday starts before sunrise, with harvesting and fieldwork lasting until mid-morning. During the hottest hours, he sorts produce in shaded areas, returning to the fields in the cooler evenings. The home needed to accommodate this schedule, serving both as a family residence and as a functional workspace for agricultural tasks.

Open Layout and Seamless Indoor-Outdoor Connection

With a generous plot of land available, the architects opted for a single-story design, maximizing accessibility and flow. The site’s original block wall was removed, allowing tractors and cultivators to enter freely from any direction. This also created an open perimeter space for storing farming tools and extending work activities outdoors.

The house features a continuous earthen floor that blurs the line between interior and exterior. A vaulted ceiling, running north to south, shelters both indoor living areas and semi-outdoor spaces beneath deep eaves. These eaves act as transitional zones, functioning as shaded work areas during the day and social spaces in the evening.

Climate-Responsive and Sustainable Roof Design

One of the home’s most distinctive features is its living vaulted roof. The top of the vault is filled with soil, providing natural insulation against Okinawa’s intense sun. Over time, passion fruit vines, bougainvillea, and other climbing plants have spread across the roof, offering shade and cooling benefits while blending the house into its natural surroundings.

The roof also doubles as a productive garden, with different soil depths allowing for the cultivation of varied crops. The owner now grows fruits and vegetables on the roof, expanding the home’s self-sufficiency. This green roof not only supports biodiversity but also helps regulate the home’s microclimate.

A Rhythmic, Light-Filled Interior

Inside, the vaulted ceiling varies in height, introducing a subtle rhythm to the simple floor plan. Gaps between the roof and walls allow soft daylight to filter in, creating a gradation of light and shadow throughout the day. The open interior is functional, uncluttered, and well-suited to a lifestyle that flows constantly between indoor comfort and outdoor labor.

The House in Shikenbaru stands as a model of context-driven design, merging architecture with farming culture, climate-responsive strategies, and sustainable living. Studio Cochi Architects has created a home that is not only tailored to its inhabitants’ daily rhythms but also deeply rooted in the agricultural heritage of Okinawa.
