charred timber wraps linear casa las tupas, topped with pitched roof in northern chile

Casa Las Tupas’ linear volume sits on the slopes of Catapilco

Casa Las Tupas is located on the coastal slopes of Catapilco in northern Chile, an area defined by its arid climate, seasonal winds, and a landscape marked by ravines and local biodiversity. Designed by Lucas Maino Fernández Arquitectos, the project responds to the clients’ objective of transitioning from urban to rural living, with a focus on low environmental impact, functional simplicity, and integration with the surrounding terrain.

The house is organized as a single rectangular volume aligned along a north–south axis. The orientation maximizes passive lighting and ventilation, with the east and west facades opening to key views and sunlight. A pitched roof descends toward the west, elevating the eastern facade to increase solar exposure while managing heat gain. This approach directly addresses the site’s environmental conditions and enhances interior light quality throughout the day. One of the primary design strategies was to maintain spatial transparency and visual continuity between interior and exterior. A linear skylight is incorporated along the eastern facade to introduce diffuse natural light, while carefully placed windows frame specific views of the landscape. The entrance is approached via a narrow wooden bridge, subtly directing circulation and framing the access point.

Lucas Maino Fernández connects architecture with context

The interior follows a linear, sequential layout based on a ‘train of rooms’ scheme. Spaces transition from shared to private zones, beginning with an open-plan kitchen, dining, and living area. A small terrace, designed for outdoor cooking or gatherings, extends this common space. To the west, a large covered terrace runs along the facade, protected by an overhanging eave with variable height, providing shade while preserving outward views toward the Las Tupas ravine.

The design team at Lucas Maino Fernández Arquitectos selects construction materials for their cost-efficiency and environmental suitability. The use of basic structural systems, untreated finishes, and an emphasis on durability supports the house’s low-maintenance and resource-conscious approach. Internally, lightweight partitions and natural lighting reduce energy reliance while maintaining a comfortable living environment.
