For an 11,840-square-foot house in Curitiba, Brazil, architect Marcos Bertoldi designed the pool and back yard as a quarry, with large Travertine slabs over flowing up into the first story and throughout the house. The residents didn’t want just any old patio pavers. Bertoldi strove for “excavated volumes, unadorned white surfaces and wide openings in an asymmetrical play of volumes and proportions.”
