Architecture in Harmony with Nature

Chilean studio Paralelo Transversal has crafted a remarkable house, Casa Ensenada, located in the scenic Puerto Varas, Chile. This 155-square-metre residence, completed in 2025, is positioned on a lush 1.2-acre site near Lago Llanquihue. The house impresses with its hip roof that extends seamlessly over a ravine, serving as a unifying design element, embodying the pioneering architectural design Chile is known for.

Architect Sebastián Silva emphasized the roof’s significance, noting, “In southern Chile, rain is not an exception, so we wanted the roof to transcend functionality. It creates a communal space beneath the rain, connecting the home’s various parts under a singular architectural gesture.”

Structural Innovation: A New Roof Paradigm

The roof of Casa Ensenada functions as more than a cover; it organizes the entire home, dictating circulation, structure, and its relation to the broader landscape. Silva describes its design: “Thickening at the center, the roof remains thin at its edges, giving it a light appearance while offering structural depth necessary to withstand Chile’s seismic activity and Patagonia‘s fierce winds.” This exemplifies the hip roof design needed to adapt to environmental challenges.

A Thoughtful Layout

The property lies on a slope adjacent to a stream, greeting visitors with a view before turning toward the main entrance that delineates public and private spaces. The narrower side of the plan contains a large, open kitchen, dining and living room, seamlessly extending onto a cantilevered terrace. The roofing architecture plays a crucial role in shaping these dynamic spaces.

With strategic northeast-facing rooms, the house maximizes winter sunlight. Expansive floor-to-ceiling windows frame views of Vicente Pérez Rosales National Park and the Calbuco Volcano, blurring the lines between indoor and outdoor environments. This integration further emphasizes the creative architecture Chile offers, blending natural beauty with modern living.

Material Elegance and Collaboration

The home’s interior and exterior harmonize through a blend of exposed concrete, extensive glazing, timber, and metal roofing. The carefully concealed joints in the roofing allow for a sleek profile, emphasizing precision in design and execution. Collaboration with engineers and local builders was key to achieving the structure’s long spans and delicate edges reflecting the celebrated roof techniques Chile is famous for.

Reflecting on the project, Silva stated, “The project succeeded in uniting architecture with its natural surroundings without compromising on comfort, logic, or budget. It underscores the power of a clear architectural vision in organizing space, materiality, and structure.”

Expanding Architectural Horizons

Paralelo Transversal’s previous projects include an innovative skylight near Santiago, showcasing their commitment to integrating nature in design. Other recent Chilean architectural achievements feature a timber forest retreat by Iragüen Viñuela Arquitectos and a seaside abode with terraces by Croxatto and Opazo Architects. Each project uniquely highlights the rich interplay between modern architecture and the stunning Chilean landscape, demonstrating the country’s pioneering approaches in roofing innovation Chile continues to develop.
