In the rural landscape of central Chile, architectural duo Mauricio Pezo and Sofia von Ellrichshausen have once again defied conventional domesticity. Their latest project, “Lima House,” completed in 2025, is a monolithic, pink-pigmented concrete sanctuary that anchors itself in a flat farmland framed by rocky hills and vineyards. Moving away from the verticality of their iconic tower houses, Lima House is a horizontal experiment in symmetry and circulation. As 2026 begins, the residence has become a focal point of architectural discourse, praised for its “mysterious and monumental” presence that balances the brutal weight of concrete with the soft, shimmering reflections of a central courtyard pool.
A Monolithic Anchor in Chépica
Located in Chépica, a rural valley in Chile’s O’Higgins region, Lima House is a 300-square-meter residence designed for a retired couple. The structure is built entirely from pink-pigmented concrete, a choice that allows the building to harmonize with the warm, dusty tones of the surrounding vineyards and rocky landscape. The exterior walls, marked by the texture of their wooden formwork, give the house a weathered, permanent quality that feels more like an ancient ruin than a modern home.
The house is oriented along an east-west axis, meticulously aligned with the path of the sun. This positioning ensures that the building captures the changing quality of light from dawn until dusk. By placing the home on a flat piece of farmland, the architects have created a “horizontal ribbon” that stretches across the site with measured restraint, offering a stark contrast to the organic, uneven terrain that surrounds it.
The Loop of Life: A Courtyard-Centric Plan
The defining feature of Lima House is its layout, which is organized as a continuous loop around a narrow central courtyard. This open-air void contains a long, slender swimming pool that acts as the building’s spiritual heart. The water draws reflected light into the surrounding rooms, introducing a quiet, shifting shimmer that animates the concrete interiors throughout the day.
Movement within the house is handled through a sequence of interconnected rooms and walkways that frame the courtyard. This arrangement encourages a “circular ritual” of daily living, where one is constantly aware of the outdoors while remaining protected within the heavy concrete shell. The architects describe this linear form as an encounter between abstract letters—a dialogue between the “T” and “U” shapes that establishes a poetic architectural rhythm.
Corner Complexity: The Quarter-Cylinder Rooms
While the overall footprint of the house is a strict rectangle, the internal layout introduces a surprising level of geometric complexity. Each of the four corners of the house contains a quarter-cylinder-shaped room, framed by elegant curved walls. These circular chambers anchor the plan, providing a sense of order and enclosure that softens the rigid perimeter.
These corner rooms serve as private sanctuaries—bedrooms and study areas—that feel distinct from the more open living and dining spaces. The transition between the straight and curved walls creates a series of dynamic interstitial spaces, making the interior feel much larger and more intricate than its 300-square-meter footprint would suggest. The interior walls are finished with wooden boards, creating a subdued, warm texture that contrasts with the bright, reflective light of the courtyard.
Material Honesty and Minimalist Restraint
In 2026, Lima House stands as a testament to Pezo von Ellrichshausen’s mastery of material variation. The duo has eschewed the “glass-box” trend in favor of structural mass and geometric clarity. The pink concrete is used not just for the structure, but as a tactile element that defines the atmosphere of every room. Small, precise openings are strategically placed to frame selected views of the vineyards and distant hills, treating the landscape as a series of curated paintings.
The house follows a minimalist philosophy where every element is essential. There is no air conditioning; instead, the house utilizes its courtyard-centric design and the thermal mass of the concrete to maintain a comfortable temperature. This sustainable, low-maintenance approach to rural living reflects a broader trend in architecture toward “passive” climate control and a return to raw, unfinished materials.
A Legacy of Geometric Purity
The architects liken Lima House to their very first project, the aluminium-clad Casa Parr, citing a similar desire to create a sense of permanent shelter for its inhabitants. As part of a larger portfolio that includes the yellow-pigmented Raem House and the cultural pavilions of the Fundación Artificial in Yungay, Lima House reinforces the firm’s reputation for creating “mental and physical constructions” that challenge our understanding of home.
As the 2025/2026 architectural reviews have noted, the house is a “monumental statement” that prioritizes self-perception and the moment. It is a residence that doesn’t just house a family; it houses a philosophy. In the quiet valley of Chépica, Pezo von Ellrichshausen have built a pink concrete bridge between the earth and the sky, proving that even the heaviest materials can be used to create a sense of weightless serenity.
