On the coast of Chile, Pritzker Prize architect Ryue Nishizawa has designed the Los Vilos House. Following the rocky terrain it occupies, the weekend retreat is topped with a wavy concrete that flows toward the water. The curves of the roofline don’t just form an organic silhouette. Its contours also define the interior’s three living spaces – a sauna in the front followed by a bedroom and gathering area, and a kitchen and dining room to the rear. Off the back, the roof unfolds to create a sheltered outdoor terrace. The sweeping canopy is supported by steel columns and walls of glazing, immersing ever room in views of the dramatic coastal landscape.
