For a journalist and an architect who want to live and work where they holiday, this 1,125-square-meter house represents a cocktail of the couple’s origins: furnishings inherited from the family are typical of the area’s former “mining farms” and there are vernacular details like the bay doors often used in local guest cottages. These are tempered with modern elements and sustainability: After taking a class in permaculture, they built a mud wall in the living room and then repurposed the wooden molds used to create it when building the poolside bathroom. They also rescued half the taubilhas (shingles) from demolitions elsewhere.
