Trillizas is conceived as a neighborhood-scale residential complex composed of three unified housing units. The proposal is defined by a series of pure, stepped volumes that adapt to the site’s topography, using a material palette that combines the solidity of stone with the transparency of large glazed openings. The design emphasizes fluidity between interior and exterior through private terraces and a careful integration of vegetation, allowing the architecture to engage in dialogue with the surrounding landscape. It is a synthesis of modernity and balance that offers a contemporary living experience within a consolidated residential environment.
