This paper presents a conceptual design of a lightweight shelter inspired by the traditional Filipino house, Bahay Kubo, aiming to meet sheltering needs after a natural disaster in the Philippines. To tackle environmental conditions, the proposed shelter alters its shape in two different spatial configurations to accommodate the Philippines’ rainy and dry seasons. For instance, during the rainy season, the shelter features a steep roof and a raised floor (vertically elliptical in shape) to protect against rain and flooding. During the dry season, the shelter can be configured to have a wider layout (horizontally elliptical in shape). Using locally available materials for the shelters’ structural and envelope system, such as bamboo beams, amakan wall panels (woven panels of bamboo) and nipa palm leaves using the pawid thatching technique for the roof, this approach not only reduces the environmental impact of the shelter but also supports the local economy. Additionally, the design incorporates a conceptual design of ball-and-socket joints, telescopic locking mechanism and an adjustable steel clamp to connect the bamboo beams with the joints in avoiding using bolted connections. Auger anchors are used to support and ensure the shelter’s stability. 3D printing technology is employed to maximize the potential of ball-and-socket joints while also considering manufacturing complexity when joining multiple links. Finally, the paper presents the structural and joint stress analysis, and a prototype in scale 1:6 which demonstrates the shelter’s transformation from the rainy season to the dry season configuration.
