On the Pacific coast of Puerto Escondido, Oaxaca in Mexico, Aranza De Ariño builds Casa Viento, three board-formed concrete volumes that choreograph wind, shade and light rather than enclosing space.
The site is dry tropical scrub, thick with acacia and cactus, the Sierra rising pale in the distance and the ocean pushing a constant breeze up the slope. Casa Viento reads less as a single house than as a settlement of three concrete volumes set among the vegetation. A central pavilion holds the shared rooms, living, dining and kitchen, and two independent bedroom pavilions sit to either side, close enough to keep a visual thread across the site, far enough apart to leave each sleeping room its own privacy.
Between the volumes, nothing. The central pavilion opens on both long sides to a covered slab that runs clear through the plan, so that wind, not corridor, connects one room to the next. Deep roof overhangs throw the interiors into shade at midday and stretch daily life out onto the terrace, where a live-edge parota table and low daybeds face the lap pool and the scrub beyond. The boundary between inside and out is left deliberately unresolved.
Exposed concrete sets the register throughout, poured against rough timber boards that leave the grain and tie-bolt holes legible across every surface. Floors are pale terrazzo, cool underfoot. Against the grey, the joinery warms the palette: teak-toned shutters, a slab dining table, a green-veined marble coffee block that catches the light like water.
The operable wooden shutters do most of the daily work. Louvered panels wrap the bedrooms and bathrooms floor to ceiling, and through the day they are swung, tilted and shut to meter sun, air and privacy. When the slats are angled, they rake the concrete with bands of striped shadow that shift as the sun moves; thrown fully open, a bedroom loses its fourth wall and gives directly onto a flowering flamboyant tree and the hills behind.
Restraint is the method. There is almost no ornament, no accent, nothing to distract from the changing light, the cross ventilation and the surrounding landscape, which are left to set the mood of the house hour by hour. Casa Viento argues, quietly, that luxury on this coast is not excess but air, shade and a durable connection to place.
