ON HOW FAÇADE/STRUCTURE ARE ONE AND THE SAME We propose a building where the architectural typology is diluted or merged with the structural type. The history of modern architecture exemplifies two typologies: the nave and the tower. In both, the steel structure is the protagonist of the spaces AND the expression of the building. We propose a building made up of an ATRIUM that evokes these diaphanous steel naves and a TOWER that follows the typological guidelines of the structural tube steel frame and its proven timeless flexibility and functionality.
