Txog Amami House Tsev

Amami House yog ib lub tsev nyob uas txaus rau tus kheej nyob rau saum Amami Island, tebchaws Nyij Pooj, npaj rau ib tsev neeg muaj plaub leeg. Lub koog povtxwv no muaj huab cua kub thiab ntsev vog, tab sis muaj tshav ntuj tsawg. Lub tsev txhawb kev nyob xis tsis tas yuav vam khom rau hluav taws xob fais fab lossis cua txias. Cov tswv yim passive xws li cua tuaj yeem ntws, kev siv tshav ntuj rau qhov pom kev thiab kev tiv thaiv kub txias ua rau tsis tas yuav siv tshuab ntau. Lub ru tsev hip-and-gable raws li kev cai qub tau raug hloov kho dua tshiab nrog cov yam ntxwv kev ua haujlwm niaj hnub no. Lub tshuab siv tshav ntuj rau dej kub, ib qho kev ua compost thiab ib lub vaj hauv tsev ua ke tiav ib lub voj voog me me ntawm kev txaus rau tus kheej.

Yam Tshwj Xeeb: Located on Amami Island, an island with a hot and humid climate and among the lowest levels of solar radiation in Japan, this self-sufficient house investigates how a family of four can live comfortably without dependence on the power grid or air conditioning.

Rooted in the island’s unique climate and culture, the design reinterprets vernacular architecture through passive strategies, including natural ventilation, daylighting, and insulation, thereby minimizing reliance on mechanical systems.

The project presents a sustainable model of living in harmony with nature, nurturing resilience, and quietly redefining what it means to dwell in the modern world.
Qhov Loj & Ntim: A vacuum-tube solar water heater installed on the east-facing roof supplies domestic hot water, reaching 60 to 97 degrees Celsius in summer and around 30 degrees in winter. Only minimal backup from a gas heater is needed, reducing gas consumption to less than half of that in the family’s previous rental home. Groundwater use was initially considered, but high iron content led to the adoption of a public water supply for greater reliability. The sauna is heated with wood repurposed from local construction offcuts, creating a circular resource exchange with nearby builders. A composting system turns kitchen waste into fertilizer for the home garden, where vegetables grown on-site return to the dining table, forming a small yet tangible cycle of self-sufficiency.

Thev Naus Laus Zis Tsim Khoom: Amami is often called the “Island of Yui,” known for its deeply interwoven social ties. Traditional celebrations for children’s milestones often bring together more than 80 relatives and neighbors, reflecting a collective culture where child-rearing is shared across families and the wider community, and homes have historically functioned as both private and communal spaces. In recent years, however, such practices have diminished due to nuclear families, standardized housing, and the impact of the pandemic. This house responds by reintroducing openness and generosity into the domestic realm, creating spaces where people can naturally gather and share time together, reviving and sustaining the island’s cultural traditions.
Kev Sib Tw Tsim Qauv: The hardest part was designing a truly self-sufficient house in one of Japan’s most demanding climates—hot, humid, and with limited solar radiation—while removing dependence on the power grid and air conditioning. Balancing comfort and resilience required continuous testing of passive strategies, energy autonomy, and spatial composition, with every decision responding precisely to local climate data. Equally challenging was integrating cultural elements such as the dispersed house form, the openness of yui community ties, and traditional roof expressions into a contemporary language sustaining both environmental and communal life.
Kev Txhawb Siab: Inspired by the vernacular landscapes of Amami, where corrugated metal roofs are commonly seen across local settlements, the design inherits the traditional hip-and-gable roof form and integrates contemporary performance features such as insulation, ventilation, and natural lighting. Through this synthesis, the project reinterprets and reconstructs the roof as a new architectural typology that connects local identity with modern functionality.
