In this building, the theme of climbing is taken as a basis. It’s dizzying and exciting. The way up becomes a real adventure. You have to go outside, then inside, then in, then out. The staircase, then narrows, then widens. The whole way is a series of contrasting sensations. At the end, the staircase converges to a single 30×30 cm cage, on which only one person can stand. And this is the most acute, culminating moment of the ascent.
