Construction costs, Aranza says, came to approximately $45,000, including “the pool, terraces, access road, and all the installations (such as water, electric, sewage, cistern, and passive solar heaters for the water in the bathroom and kitchen).” Aranza hired her crew using members of the team that built the nearby Casa Wabi, a Tadao Ando-designed artist’s retreat and foundation established by Claudio’s brother, painter Bosco Sodi (tours arranged on request for Casa Tiny guests). Aranza explains that the circle pattern on the walls is from the in-situ casting: “It’s through those circles that the wooden ‘mold’ is tied together to make it possible to pour in the concrete.”
