Loma Sagrada House

Loma Sagrada House, designed by Salagnac Arquitectos, is a regenerative residential project located in Nosara, Costa Rica. The project transforms a site previously degraded by livestock farming into a thriving ecological environment, redefining the relationship between architecture and land restoration. Unlike conventional construction methods that often damage natural ecosystems, this project actively contributed to the regeneration of soil, vegetation, and microclimate during the building process. The architectural strategy is based on minimizing impact. Structures are elevated on stilts and constructed with minimal earth movement, allowing natural vegetation to recover even during construction. The main residence is positioned on the southern slope of a hill, where it is naturally protected from strong seasonal winds. This placement also creates a favorable microclimate, where surrounding vegetation cools the air and enhances indoor comfort without relying on mechanical systems. The building adopts a triangular structural concept that uses the terrain as part of its geometry. This innovative approach reduces the need for foundations to only a few contact points, preserving the land while ensuring structural efficiency. The entire house is organized through a modular wooden system, enabling precise fabrication and efficient assembly. The elevated design also allows uninterrupted views of the surrounding jungle canopy, reinforcing the connection between interior spaces and the natural environment. Materiality is central to the project’s identity. Approximately 95% of the construction is made from plantation-grown wood, used in structure, floors, walls, ceilings, and furniture. The use of wood contributes to carbon absorption, regulates humidity, and creates a healthy indoor environment. The use of concrete and metal is intentionally minimized to reduce environmental impact. In addition to passive strategies such as natural ventilation, solar protection, and thermal insulation, the house integrates sustainable systems including solar energy, water reuse, low electromagnetic radiation electrical systems, and chemical-free water purification. The landscape design combines natural regeneration with permaculture and native planting, transforming the entire property into a living ecological system. Loma Sagrada House represents a holistic approach to architecture, where sustainability, health, and spatial quality are fully integrated. It stands as a model for regenerative design, demonstrating how architecture can actively improve its environment while offering a deeply connected living experience.
