Porto 1820 redefines Porto Alegre’s skyline through an architecture in dialogue with the Guaíba River. The building features 26 residences, each designed as a frame in concrete and wood to capture ever-changing natural views. Its facade, resting on a monolithic stone base, results from the precise arrangement of cantilevered frames up to 3 meters, creating a symbolic and harmonious integration between the urban and the natural.
