Copas House is a minimal residence located in Valle de Bravo, Mexico, designed by PPAA. The key aim was to craft an open upper floor that seamlessly integrates with the treetops, fostering a unique connection with nature and shaping the house’s ambiance and vistas. The design of Copas ingeniously adapts to the site’s natural topography, utilizing the slope to minimize excavation. By elevating the public spaces above ground level, the architecture introduces a series of platforms that blend effortlessly with the environment, offering various ways to experience the surrounding nature. The upper floor, a highlight of the project, directly connects with the treetops, enhancing the residence’s essence and offering uninterrupted views. In contrast, the first floor, housing the bedrooms, provides the necessary privacy and tranquility.
