Located within a dense eucalyptus forest 40 kilometers from Rosario, Argentina, La Ballena by Brigati–Polak Arquitectos reinterprets domestic architecture through material honesty and environmental adaptation. The home combines a monolithic concrete structure with geothermal and solar systems, achieving long-term resilience, low operational energy, and a seamless connection to its natural setting.
The forest shapes the building's layout and gives it a distinct identity: the architecture does not dominate the site but coexists with it, recognising time and nature as equal protagonists.
Concept and poetic vision
Brigati–Polak Arquitectos treat each project as an evolving study in contemporary living. La Ballena is conceived as a living organism, capable of adapting to changes in family life and environment.
Spaces invite reflection and renewal, balancing openness and shelter, collectivity and solitude. Diagonal paths and transparent planes maintain a continuous dialogue with the eucalyptus forest, transforming daily life into an immersive experience of light, scent, and texture.
Environmental approach
La Ballena’s sustainability is rooted in measurable performance rather than certification. Passive design strategies, including orientation, cross-ventilation, and deep overhangs, reduce operational energy by more than 60 percent compared to typical homes. Geothermal systems harness the earth’s crust for heating, cooling, and water production, while rooftop photovoltaic panels generate 20 kW of renewable power. Rainwater harvesting and the reuse of greywater support irrigation and reduce potable water demand.
Spatiality and program
The project reflects new ways of contemporary living: flexible spaces, blurred boundaries between public and private, and the balance between gathering and solitude. Avoiding repetition and formula, each space gains meaning through its relationship with the forest. Transparency, diagonal paths, and strategic openings establish a lasting link with the eucalyptus trees, integrating home life into a landscape of shade, scent, and memory.
Materiality and technology
The home's materials—concrete and wood for structure, glass and steel for lightness—combine integrity with poetic expression and connection to nature. Reinforced concrete provides thermal inertia, durability, and low maintenance, serving as both structure and finish to reduce embodied energy. Glass, steel, and local eucalyptus wood balance permanence and transformation.
Crafted by local artisans, eucalyptus panels and shutters age gracefully through natural oil treatments. The materiality explores permanence and change, weight and lightness, refuge and openness—expressing its historical context through technology. Geothermal energy supports air conditioning, water systems, and solar integration.
This home is not an isolated object or authorial gesture, but part of the forest and its time. It stands as an architectural essay—observing how living evolves, proposing new ways of life, and resisting repetition through constant exploration.
Durability in design
Durability and adaptability replace disposability. The open-plan layout and non-load-bearing partitions allow spaces to evolve with family needs. Material honesty ensures longevity: exposed concrete and solid timber can be refinished or reused across multiple life cycles. Rather than planning for dismantling, the architecture embraces permanence as sustainability—building once, building to last.
