The Manzoni underground project is a synthesis of the collaborative relationship between brand and architecture, in which the guidelines of the new brand are reflected in the architectural design. The red band of the Atac brand becomes an architectural object and develops in the space in a plastic form, within an environment where the choice of materials and neutral tones emphasise its presence. Stratified glass panels, steel and Corian are the materials that characterise a highly contemporary entrance in which a glass and steel parallelepiped of the information box is placed. The internal route ends, via escalators, in the underground waiting platform, covered with curved white Corian caps.
