Gare du Nord
The organisation of the various flows between departures and arrivals, together with the development of the necessary surfaces for accommodating services and facilities, had to meet new aspirations, thus offering the opportunity to rethink the overall design and its relationship with the city. The creation of a single entrance, an immense loggia opening onto the forecourt to the east of the historic station, gave access to an internal street, 300 m in length and covered by a glass roof designed in accordance with a Voronoi diagram (a type of pattern frequently found in nature, for example the configuration of the nervures of dragonfly wings). This architectural handwriting, intended to create a poetic image of freedom and lightness, also created a pathway of light crossing the new building, guiding users towards the departures to all destinations and serving the new facilities – retail, cultural, sports and coworking.
