This terminal is envisioned not just as an airport expansion, but as a cultural threshold—a space of pause, encounter, and reflection. It reimagines transit as experience, transforming waiting into wandering. Inspired by the metaphor of a cavern, the design creates layered voids, sky gardens, and interstitial gaps that invite exploration. Rather than enforce movement, it encourages flânerie. Travelers are free to dwell, to feel, to be. The terminal becomes soft infrastructure—a “Palace of Joy” that embraces emotion, plurality, and impermanence. It is not a boundary, but a beginning; not just a gateway to the world, but a place where the city speaks through space.
