Grand Paris Express
Thiais-Orly station
Each of the station’s faces is opened up by a huge arcade which communicates with the concourse. The interior space is designed as a large groin vault with taut lines, which lets light through from the sky. The intersection of the four cylindrical vaults emphasises the project’s cardinal orientations. This arrangement allows daylight to penetrate deep into the station. This natural lighting thus accompanies the movement of the superimposed escalators, made of steel and glass, which lead to the station platforms located below. Ascending and descending thus becomes a real experience for users.
The concourse’s diagonal-rib roof, thanks to the quality of the light diffused within the interior space, evokes the vault of the heavens. This is the characteristic exploited by Lyes Hammadouche when designing his sculptural installation combining satellite-like objects and projections.
