The Casas da Encosta ensemble, designed by SIA arquitectura, brings together a main house and four smaller guesthouses, each almost identical in size. The architects—Ana Cravinho, Inês Cordovil, and Sofia Pinto Basto—opted for a language rooted in the traditional architecture of this coastal region of Portugal, using honest, elemental materials like wood and lime plaster.







The design follows the model of a large patio house, with a central garden-courtyard around which the five volumes are discreetly arranged. These buildings, at once open and secluded, form a private, tranquil retreat, where the omnipresent dune—both inside and out—and a restrained, consistent color palette evoke a sense of timelessness, as though these simple, fragile-looking homes had always belonged here, like the elder residents of this land.






At the highest point of the site, the main house rises. A central volume with a traditional pitched roof is flanked by two perpendicular wings, framing a generous living room and a spacious wooden porch that opens directly onto the central garden. This space becomes a place of shade and shelter—an architectural threshold between home and landscape.

SIA arquitectura
“Founded in 2007, our practice began with the decision to inhabit a house. Not just to live in the city, but to seek out the sense of comfort we believe the city can offer. We chose the site, the street, the valley view, the program—and the risk of taking on the full process. Architecture requires decisions made from the conviction that small-scale, rigorous, and relevant actions naturally amplify over time. This is our moment, and our context. Listening is the practice of our profession.” —SIA arquitectura
