Casa Abierta proposes an architecture where simple elements, basic materials, light, shadow, and the relationship between the fabricated and natural are used to produce space and form. Habitability is the result of a series of equally significant interior and exterior areas, defined by their correspondence in a linear sequence that accommodates topography, program, and continuous vistas to the surrounding landscape.

The house was designed for a young family of four who wished for meaningful living spaces that support the intimacy of everyday life, but can also open up for special extended family activities. The location is a suburban lot within an access-controlled community in the outskirts of Ponce.
