Mexican practice Espacio 18 Arquitectura has designed a concrete seafront home on Zapotengo beach in Oaxaca, the La Casa del Sapo. This layout creates a series of triangular patio spaces, with a large central terrace overlooking the sea to the south and two more intimate spaces to the north, divided and shaded by the eastern block’s high concrete wall. Driven by the site itself as “two stones looking at the sea, craving for its timelessness”, the dual volumes are arranged in a butterfly format that makes way for triangular patios. 
The beachfront residential architecture is informed by a muted aesthetic, and material palette consisting of concrete, terracotta tiles, bricks, as well as locally sourced timber and stones, streaks of cement grey, sparkling blue, brown-red, and light beiges dressing pocket patios, doorways, and rooms of the home. The materials employed in the simple and warm interior design as well as the Mexican architecture mirror and blend into the rugged and calm nature of the site, such as rough and unfinished cement, wooden accordion doors, herringbone terracotta tiles, and a steel and branch canopy that blesses the large central patio.
