​

Casa Olivos is situated on a sloped site in northern Santiago and employs a prefabricated reinforced concrete structure as its primary construction system. The design emphasizes energy efficiency and sustainability, integrating passive strategies and low-impact technologies.​

The house is oriented toward Mount Aconcagua, the highest peak of the Andes, visible on clear days from the second level. This visual connection reinforces the dwelling's relationship with the Andean landscape.​

The lower level rests directly upon a large existing rock, incorporated into the project as both a structural element and a natural thermal mass, helping to regulate indoor temperatures throughout the day.​

A cross-ventilation system ensures the circulation of fresh air across both levels, enabling efficient passive climate control. Additionally, the residence features a greywater treatment and reuse system for irrigating the garden's vegetation.​

The use of prefabricated concrete panels reduced construction time and minimized on-site waste. The thermal envelope, the design of overhangs, and the strategic orientation of openings provide an efficient architectural solution, coherent with the region's climatic and geographical context.
