Named after the suliformes genus of seabirds, the SULA cabin by architect Diana Salvador is a prefabricated, A-frame home designed for the unique environment of the Galápagos Islands. Completed in 2023 on Santa Cruz Island for a local family, the project showcases an innovative approach to sustainable construction by minimizing environmental impact in a delicate ecological region.

The two-story, modular cabin was prefabricated over two months in Quito, Ecuador, before its 2,000 custom-made components of wood, metal, aluminum, and glass were shipped in containers to the island. The components, held together by over 17,000 screws and pins, were assembled on-site in just four weeks by a specialized team. This prefabrication process avoided construction site damage to the soil.

Inspired by bioclimatic principles, the cabin was elevated off the ground to allow for a cooling air chamber beneath it. A double-layered wall and roof structure, along with perforated floors, promote natural cross-ventilation, ensuring a comfortable interior climate. The five main materials—wood, stone, metal, glass, and PVC—were chosen for their efficiency and minimal ecological footprint. The interior features plywood paneling, creating a warm, inviting atmosphere that contrasts with the exterior.

The main A-frame structure creates a double-height central space. A loft accessed by a sliding black metal ladder offers a flexible area for sleeping, working, or leisure. Large windows at each end of the cabin, along with two narrow windows on the sides, fill the space with natural light and frame views of the surrounding nature.

The cabin was intentionally designed with scalability and relocation in mind, using gabions as foundations to further minimize the impact on the soil.
