Designed by Chilean studio Pezo von Ellrichshausen, the Lima House is a striking monolithic residence embedded into a steep coastal landscape in Los Vilos, Chile. Conceived as a retreat for a retired couple on farmland near Chepica in the O’Higgins Region, the project is constructed entirely from pink-pigmented concrete, a deliberate material choice that mirrors the warm, mineral tones of the surrounding soil. The muted rose coloration gives the house a sense of permanence and archaic gravitas, while its responsiveness to shifting daylight animates the otherwise austere façade.
At first glance, the house appears rigorously simple in plan—a clean rectangle—but closer inspection reveals a more nuanced spatial composition. Curved walls form quarter-cylinder rooms at each corner, subtly disrupting the rectilinear logic and introducing variation throughout the interior. Some of these spaces turn inward toward a central pool, while others open outward to sweeping views of vineyards, agricultural fields, and distant mountains. This arrangement produces a fluid sequence of interconnected rooms, where distinctions between public and private zones dissolve through repetition and rhythm.
Each room is capped with a high vaulted ceiling punctuated by a central skylight, allowing natural light to penetrate deep into the concrete mass. As the day progresses, light and shadow shift across the surfaces, lending the interiors a quiet dynamism despite their heavy materiality. The architects describe the plan as a “fictional encounter between two alphabetical figures, T and U,” a conceptual reference that underscores the dialogue between linear and curved geometries.
Oriented along an east–west axis, the house tracks the movement of the sun, with openings that alternate between opacity and transparency to balance privacy and openness. Sliding glass doors define more intimate areas, where recycled timber boards line the walls—an echo of the wooden formwork used during the concrete casting process. These tactile details soften the rawness of the structure and reinforce a sense of material continuity.
Through its restrained palette, geometric experimentation, and sensitive siting, the Lima House exemplifies Pezo von Ellrichshausen’s ongoing exploration of concrete as both structure and atmosphere—rooted deeply in place, yet timeless in expression.
