The challenge
More than one hundred years old. More than a billion travelers a year. The Underground in Paris. Liable to wear out. An extensive renovation plan for this lifeline must ensure the quality of life in the 21st century. Without stopping even one single train.

The approach
Station renovation demands attention and planning. Time pressure. Working within a millimeter. Underneath the city. Multiple land use. With a sense of history. Because metro stations are underground monuments. A speeding train races by a platform on which people work. Entrance, ticket sales, stairways, lighting, safety, platforms, signage. Change toward the future.

The result
Passage. Speed. Confort. A city at your feet. To enjoy. To love. To feel. To travel through.
