Sustainable Farming and Local Context


The owner of the Studio Cochi Architects-designed ‘House in Shikenbaru’ is a farmer, cultivating a variety of vegetables including okra, green beans, and papaya. With a focus on sustainability, the architects consider the owner’s farming activities and aim to provide a conducive environment for his work. The site’s location near fields and the absence of snow or frost in Okinawa enables year-round vegetable cultivation, which influenced the architectural decisions. The house becomes a vital element in supporting the owner’s farming endeavors, allowing for efficient operations and seamless transitions between indoor and outdoor work areas.

Spatial Considerations and Layout


To create a functional and adaptable living space, the layout and volume of the House in Shikenbaru were carefully planned, taking into account the surrounding environment and prevailing wind direction. Given the spacious site, the decision was made to construct a single-story house. The removal of the original block wall facilitated easy access for tractors and cultivators from any direction, creating a versatile environment conducive to agricultural activities. Additionally, a vacant lot was designated around the building, providing storage space for farming tools and ensuring a smooth workflow that integrates both indoor and outdoor tasks.

Seamless Integration of Interior and Exterior


The architectural design of the House in Shikenbaru employs a simplistic yet elegant approach to seamlessly blend the interior and exterior spaces. A continuous vaulted ceiling, varying in height, unifies the indoor and outdoor areas. Stretching from north to south, this vault crosses the boundaries between the interior and the garden, forming a semi-outdoor intermediate space.


With deep eaves, this area serves as a hall for daytime farming activities and fosters a connection between the occupants and the surrounding natural environment. The rhythm of the continuous east-west vaulted ceiling creates a sense of visual harmony within the simple plan, while the interplay of natural light through the roof and wall gaps produces a subtle and captivating gradation of light and shadow.

Environmental Adaptations


The House in Shikenbaru effectively adapts to the demanding Okinawan climate through innovative architectural choices. The valley at the top of the vaulted ceiling is filled with soil, providing insulation against the intense sunlight. This strategic design element helps regulate the indoor temperature, ensuring comfort for the residents and protecting delicate crops.


Furthermore, the entire surface of the vaulted roof is covered with vibrant ivy plants, such as passion fruit and bougainvillea. This living roof not only enhances the aesthetic appeal of the house but also contributes to environmental sustainability and acts as a testament to the owner’s commitment to cultivating fruits and vegetables in diverse soil depths.
