Forest House by Triangular

Set within a dense native forest of hualles and ulmos in Cunco, Chile, Forest House by Triangular is a sensitive architectural intervention that prioritizes coexistence with nature. With distant views toward Colico Lake, the house is carefully positioned to minimize disruption to the existing ecosystem, allowing the surrounding vegetation to remain an active and defining presence throughout the site.

Rather than clearing the land, the project gently touches the ground. The structure rests on a concrete base that elevates the house above the forest floor, enabling wild flora to grow beneath and around it. This approach not only reduces environmental impact but also protects the building from ground moisture, ensuring durability in the humid forest climate.

The architectural concept begins with a simple rectangular form oriented toward the northeast to optimize sunlight. This geometry is then fragmented and separated to preserve existing trees, resulting in two elongated volumes. These parallel bars face a natural clearing within the forest, which becomes both a central garden and a vital source of solar exposure. The clearing acts as a spatial anchor, organizing the house while enhancing light penetration and views.

The internal organization responds to the dynamics of family life, particularly the dual need for shared experiences and individual privacy. The house is designed as a flexible retreat for vacations, where multiple users can coexist comfortably. Four distinct zones: family, parents, children, and guests, are distributed across the two volumes. Interior courtyards act as separators, ensuring independence between areas while maintaining visual continuity with the surrounding forest.

These volumes are connected by glazed bridges that traverse the landscape, creating moments of transition where occupants are fully immersed in nature. Moving between spaces becomes an experiential journey, with the forest constantly present through framed views and filtered light.

Orientation plays a crucial role in the spatial arrangement. Bedrooms are positioned to receive gentle morning sunlight, creating calm and intimate atmospheres, while social areas are oriented toward the stronger midday and afternoon light, supporting more active and communal uses. This careful calibration of light enhances comfort and reinforces the daily rhythms of inhabitation.

Materiality draws inspiration from the image of a burned log, charred on the outside yet protected within. This concept is translated architecturally through a layered envelope: a metallic exterior cladding shields the structure, while warmer materials such as acetylated wood and pine define the intermediate facades and interior spaces. The contrast between the protective outer shell and the inviting inner surfaces creates a rich sensory experience.

Constructively, the house combines a solid concrete plinth with a lightweight system of prefabricated wooden panels and frames. This hybrid approach allows the building to adapt to the sloping terrain while maintaining structural efficiency. Prefabrication also reduces construction time and environmental disturbance, despite the complexity of the irregular geometries and roof articulations.

The roof design introduces subtle breaks and openings that frame views of the treetops and allow natural light to filter deep into the interiors. These apertures reinforce the connection to the forest canopy, making the changing seasons and shifting light conditions an integral part of daily life within the house.

Ultimately, Forest House is a refined exploration of architecture in dialogue with nature. Through careful siting, thoughtful material choices, and a spatial strategy rooted in flexibility and light, the project creates a living environment where boundaries between inside and outside dissolve, and the forest becomes an inseparable part of the home.
