Visitors to these slender, stacked rental cabins are granted unrivaled access to the Chilean coastline. To create such a remarkable experience, however, Santiago firm Croxatto & Opazo Arquitectos had to overcome a set of challenging constraints: a limited budget, steep slopes, and blustery coastal winds. "It was an interesting exercise in how to propose good architecture with scarcity," says cofounder Felipe Croxatto. In the end, the constraints might be to thank for the incredible results. The pair of guest cabins feature interiors in light-colored pine treated with natural oil finishes. Each has an open-plan living/dining/cooking space on the ground floor, with a lofted sleeping space above. Floor-to-ceiling windows, large glazed doors, and north-facing terraces connect the pair to the spectacular site. All construction for the cabins—including utility and road access—was completed on-site in eight months.
