Take No Hari is a microhome designed by a group of architects from Bulgaria, Bhutan, Italy, and Singapore. Located in Nagano, Japan, the project responds to issues of urban overpopulation, particularly as more people are moving from Tokyo following the pandemic. The design merges Eastern and Western architectural ideas, drawing inspiration from traditional forms like Trullo and Baso structures.

Layout and Spatial Organization

The microhome's layout features two main areas: a larger space for living, eating, and working, and a smaller area intended for sleeping. This clear separation allows for a balance between social interaction and personal time. The sleeping area includes bamboo screens that provide privacy when needed, making the space flexible for different activities and experiences.

Natural Light and Interior Experience

A central feature of the design is a skylight, which allows sunlight to fill the interior. This brings warmth and brightness into the home, improving the living experience. Furniture is arranged along the curved walls, preserving open sightlines and connecting occupants with nature outside. Such a focus on natural light supports well-being, making the microhome a pleasant place to reside.

Materiality and Sustainability

Take No Hari emphasizes the use of low-embodied materials alongside traditional construction methods. The roof resembles the Gassho style, utilizing Susuki, or water reeds, with solar panels incorporated for energy efficiency. Walls consist of a combination of bamboo and cedar, with rice husk insulation that aids thermal comfort. These material choices reflect a commitment to sustainability while ensuring durability and functionality.

Design Detail and Contextual Integration

The microhome is raised on a wooden deck that can serve as a gathering space for picnics and outdoor activities once the structure is no longer in use. This design choice aligns with principles of sustainable living and shows an understanding of the local environment. Positioned within a bird sanctuary, the home enhances both the aesthetic and functional qualities of its setting. The overall architectural approach honors traditional values while addressing contemporary living needs.
