With only 88m2, a front of 5.50m facing Av. da Boavista and 2.00m wide on the rear elevation, the plot is characterized by its small size. With only two facades to capture natural light, we completely opened the elevations, intertwining the openings in elegant concrete arches that draw the facade and give it a strong personality. Through a complex typological game, we optimized the space to the maximum, integrating 11 typologies in 649 m2 of gross area.
