Designed with a mechanical system, the Casa Ojalà is a modular nature retreat. The tiny wooden structure can open and close walls and ceiling to immerse those inside in views of the surround landscape. While compact, its 290-square-foot interior has all of the luxuries of a hotel room with two bedrooms, a bathroom, and living area. There’s also space on the rooftop for an elevated terrace. Equipped with self-contained electrical and water systems, the shelter is off-grid capable allowing for installation in remote mountain tops or isolated beaches.
