Casa Areia is pure nakedness and muteness. The platonic suggestion—a sea cottage with sandy floors—is a serene search for simplicity. Sandy ground and wooden frames are an apparently simple attempt at making the space a reciprocal relationship with the beach landscape. The design begins with the conditions of the materials, according to their potential habitability.

Each masonry building was adapted to individual rooms, while one of the two wooden volumes was converted into a two-bedroom pavilion and the other a common area. The exterior and interior wall partitions of the common space have been created with bamboo, and a natural roof tops off each of the constructions on site.
