This project envisions a mountain refuge embedded in Taiwan’s Central Range, using terrain, geothermal, rainwater, and biodiversity to achieve resilient, self-sufficient living. Clustered vertical caves form an ant nest-like network for decentralized survival. Each unit links living, public, and resource zones, with systems for water harvesting, farming, and energy. Entrances are hidden and structures integrate with the mountain. Compared to flatland shelters, this model ensures better resource access, concealment, and adaptability, minimizing external reliance.
