A threshold is the lower surface of a doorway, the physical boundary that marks the exact transition from one space to another.
The scene is built from an elevated perspective, as if the viewer were standing halfway down a staircase. From this position, the architecture organizes an empty lobby where the staircase, the hallway, and the doors form a suspended space of transit. A vending machine and an emergency bar indicate the functionality of the place and its condition as a space intended for movement. However, the absence of people interrupts this use and deactivates it, the space is reduced to its transitional condition. It becomes a non-place, an intermediate territory defined solely by existing in the in-between, without ever becoming one thing or another.
