Sustainable development on remote islands encounters hurdles such as environmental, logistical, and economic constraints. Small islands face insufficiency and limitations in construction materials due to limited natural resources. Lightweight structures emerge as transformative solutions to overcome challenges in construction. Santiago Island faces construction complications intensified by adverse weather and logistical issues, particularly disruptions in material transport. This study proposed a lightweight structure by addressing logistical challenges, environmental challenges, and structural costs, assessing existing materials including bamboo, exploring sustainable design principles, incorporating structural standards, and constructing and evaluating a typhoon-resistant structural system. The study results of the identification of lightweight construction materials and techniques available on Santiago Island and the investigation of a sustainable design system, which is the A-frame house design or triangular-shaped structure, foster sustainable development and resilience for remote islands. Structural analysis of the lightweight sustainable design was also identified through STAAD to comprehensively check all the structural members. The results of the research propose a hopeful remedy for crafting a cost-effective, environmentally friendly, and durable architectural blueprint tailored specifically for communities residing on small islands within low- to middle-income nations.
