Casa Duarte Passanha, crafted by Gonçalo Byrne, is a masterful embodiment of modernist principles, tailored for a young family with three daughters. The design is a compact yet dynamic structure, unfolding over three staggered floors. Byrne’s approach is deeply influenced by the architectural philosophy of Adolf Loos, focusing on functional simplicity and spatial clarity. He describes it as “the most Loosian project” he has ever designed, emphasizing the purity of form and the strategic use of space.

The building ingeniously inverts the original 1930s structure, reorienting the main living areas towards a previously neglected courtyard. This transformation turns the courtyard into a central feature, effectively making it an amphitheater that the house embraces. The living spaces and bedrooms, positioned on the upper floors, are designed to capture the full depth of the plot, extending the interior into the exterior environment seamlessly.

Byrne’s vision was to create a harmonious interaction between the indoor and outdoor spaces, enhancing the family’s connection to their surroundings. The use of large windows and open spaces allows natural light to flood the interiors, creating a warm and inviting atmosphere. The materials chosen for the construction, likely a blend of concrete, glass, and wood, reflect a commitment to durability and aesthetic appeal, aligning with Byrne’s philosophy of timeless design.

The building’s orientation and layout not only maximize the use of space but also create a series of intimate and communal areas that cater to the family’s lifestyle. This thoughtful design ensures that each room has a unique relationship with the courtyard, fostering a sense of openness and continuity throughout the home.
