Berna House by Hiro Arquitectos Challenges Traditional Peruvian Construction with Exposed Brick and Lime Wash

In contemporary architectural design, the finishes applied to a building often serve to conceal the raw labor and underlying materials of construction. Plaster, paint, and sleek cladding panels are routinely deployed to create smooth, uniform surfaces that mask the structural reality beneath. However, a striking new residential project in Peru—curated by Valentina Díaz and captured through the lens of architectural photographer Renzo Rebagliati—invites a radical reassessment of this common practice. Designed by Hiro Arquitectos, the newly completed Berna House upends conventional Peruvian construction methodologies by celebrating the unvarnished materiality of brick masonry, transforming what is typically hidden into the defining architectural feature of the home.

The standard procedure across much of the Peruvian construction industry relies heavily on brick masonry, yet structural bricks are rarely permitted to remain visible in the finished building. Instead, traditional masonry is constructed, heavily plastered over, and ultimately buried beneath layers of finishing coats. This conventional approach aims for a pristine, homogenous aesthetic, entirely erasing the tactile quality of the individual units and the physical effort required to assemble them. Berna House begins its conceptual and structural journey by deliberately reversing this established practice. Rather than hiding the masonry behind smooth walls, the architects choose to leave the brick walls exposed, exposing the raw texture of the structure to both internal and external environments.

To achieve a refined yet honest aesthetic, Hiro Arquitectos finished the exposed brick surfaces with a delicate lime wash. This intentional application serves a dual purpose: it lightens the visual weight of the brickwork without completely concealing its inherent character. By utilizing a lime wash rather than an opaque paint or heavy plaster, the architects allow the fundamental qualities of the material to breathe and remain perceptible. Consequently, the meticulous bond, the precise mortar joints, and the subtle, organic irregularities of the bricklaying process remain entirely visible. This architectural treatment is applied thoughtfully across key zones of the residence, most notably along the prominent entrance wall, the sweeping garden-facing facade, and the intimate gathering spaces of the main living room.

Rather than being driven by superficial or purely aesthetic whims, this design choice represents a deeply foundational construction decision. The architectural character of Berna House emerges directly from the logic of its assembly and the physical properties of its chosen materials. By stripping away unnecessary layers and decorative artifice, Hiro Arquitectos establishes a dialogue between raw materiality and refined architectural composition. The texture of the brickwork, softened only slightly by the translucent lime wash, interacts dynamically with changing daylight throughout the day, casting gentle shadows across the living room and highlighting the craftsmanship embedded in the garden-facing facade.

Published on September 24, 2026, the completion of Berna House highlights an ongoing evolution in contemporary architectural practices across South America, where local studios increasingly seek to honor indigenous construction materials and techniques while maintaining a modern sensibility. Through their thoughtful approach, Hiro Arquitectos demonstrates that structural honesty can coexist with sophisticated spatial design, offering a refreshing counterpoint to the hyper-finished aesthetic that dominates much of modern residential architecture.
