Los Carlos House: Sustainable Coastal Retreat by ap22.arq in Reta, Argentina

Nestled within the unique coastal landscape of Reta, Argentina, Los Carlos House, designed by ap22.arq, is a modern beach residence that balances family life, nature, and sustainability. Completed in 2024, this 94 m² home serves a couple and their three teenage children, offering a flexible, open-plan layout ideal for summer gatherings with friends.

Contextual Design Amidst Coastal Dunes

Reta is a seaside resort defined by its dynamic dunes, some stabilized with tamarisks, cortaderas, pampas grass, and cat’s claws, while others shift naturally from west to east under the influence of coastal winds. The architects embraced this raw, evolving landscape, choosing a building site that preserves the natural environment while maximizing panoramic views. The house’s placement also takes advantage of a pre-existing grove of trees that shields it from strong southwest winds, a crucial feature against seasonal sandstorms.

Linear Plan with Expansive Gallery

The design draws inspiration from childhood memories of linear homes that extend into galleries full of greenery, fostering communal spaces for family life. The linear floor plan places the living-dining area and master bedroom at opposite ends, both oriented toward breathtaking coastal vistas. Between these primary spaces lie two smaller bedrooms and a second bathroom, ensuring privacy and functionality for the entire family. A large gallery extends from the main structure, creating an inviting indoor-outdoor transition perfect for summer living.

Sustainable Materials and Construction

Sustainability was central to the project. The house is primarily constructed from reforested eucalyptus wood, featured in the walls, ceilings, and floors. Wall assemblies combine 1” eucalyptus tongue-and-groove boards with a 1” x 4” structural framework housing thermal insulation, finished with phenolic plates and vertical planking for rustic charm. The tongue-and-groove floors are polished and coated with three layers of natural protectors, mounted over insulated phenolic panels for durability and thermal efficiency.

High-performance white aluminum joinery with double glazing and an air chamber ensures energy efficiency while maintaining visual lightness. Despite the remote location, the project was realized efficiently with a small team of local builders and carpenters from Misiones, highlighting the potential of skilled regional craftsmanship.

Harmonizing Nature and Modern Living

By raising the structure above the sandy terrain and carefully integrating with the site’s natural elements, Los Carlos House demonstrates a respectful approach to environmental preservation. The project merges coastal architecture, family-oriented design, and sustainable construction, creating a serene, functional, and visually striking summer retreat.
