10-Storey Spiral Stairs Made with Escalators

Star Place is a new Taiwanese department store designed by Dutch architects UNStudio. Outside, the building is beautiful, with a curved façade that glows in a weird star-like moiré pattern. However, the best part of this structure is inside, in its 10-storey atrium, where the designers have constructed a spiral stair made by rotating escalators over a central axis.
