© SGP - The 15th west line of “Grand Paris Express” will link Pont de Sèvres to Saint-Denis Pleyel (21 km, 9 stations). It will open in 2025.The project of Grand Paris Express metro station the seeks to optimize the way in/out of travelers. The journey from the city to the metro platforms at 36m depth is composed of "scenes" articulating the space. It is thanks to simple regulatory geometries (the circle, the square and the cube) that the sequences and the spaces are ordered in this set of infrastructures. - The circle: the self-stable well - Firmitas The optimization of the structure with a self-stabilizing cylindrical shape serves to reduce the effects of the thrust of land on the buried structures and to remove buttresses that would have cross the central space. The volume is then free and the space entirely devoted to vertical links in order to enhance the clarity of the flows. - The square: "ambulatory" escalators - Utilitas The optimization of the floor levels, using large escalators (17 m footprint) capable of crossing a height of about 10 meters, provides an improvement in travel times and a financial gain on structural works. Its location and distribution follow a square outline. This arrangement makes it possible to generate a "square" hopper of 25 meters around which passengers can walk. The transit spaces become balconies on a central void that announces the sequence of decent or rise. The travelers then become the involuntary actors or the spectators of a perpetual movement ascending and descending. - The cube: the cloister of light - Venustas This is the heart of the train station beating: the rhythm on the rail traffic of the station, the unit of sequencing travel sequences, the unitary and monumental identity of the station, a volume with a great theatrical strength and finally the readability space of the optimized courses.
