The pace set by our current life, forces cities to be at the service of man and to give us the speed we need today. The underground allow us to manipulate the space-time connection, as a tool of comfort and modernity. It creates an underworld with a strong complexity that runs under the city, as a reflection of the surface. The union between the two worlds creates a very personal architecture that identifies this interconnection, linking both realities and giving a symbolic and even iconic object to the city. Inside we find soft, organic, humane forms and natural light. On the outside we built a more regular shape, to dialogue with the urban landscape.
