Located in the heart of the Pyrenees mountain range in northern Spain, Una Nevera Azul is a small, self-sufficient cabin designed and built by its owners. This bespoke micro-cabin, with a 29 m² (312 ft²) interior and a 12 m² (129 ft²) wood-decked terrace, serves as a retreat focused on slow living, environmental integration, and structural autonomy. The design process began with a collection of reclaimed materials, including old glass panels, windows, and doors, which influenced the architectural layout and character of the cabin. The owners, a cabinetmaker and an interior designer, utilized these elements to create a home that reflects a resource-conscious approach to construction. Una Nevera Azul operates independently from conventional energy sources, utilizing solar power and low-consumption systems. Heating is provided by a wood-burning stove, with gas used for cooking and hot water. The architectural design dissolves the boundary between the interior and the rugged mountain landscape, featuring expansive window apertures that capture panoramic views and maximize natural light. The creators employed advanced digital and physical drafting techniques to optimize the cabin's orientation for solar heat gain and natural lighting. The interior layout maximizes verticality and volumetric efficiency, integrating a compact kitchen, sleeping zones, and living areas into a cohesive living space. The project took a total of 4 months to complete, involving two primary builders and additional assistance for a few days, encompassing both design and construction phases, resulting in the house as it stands today.
