The Gangnam Intermodal Transit Center is a project that leverages the potential of subterranean architecture by creating an integrated station for five regional and local rail lines, a bus transfer hub, and public and commercial facilities beneath Yeongdong-daero. Junglim Architecture established a clear vision early on, based on its deep understanding of the site gained through the initial Yeongdong-daero Underground Space Development conceptual study. Collaborating with Dominique Perrault Architecture, who has extensive experience in underground development, the team pursued a balanced design focused on ecological stability and the philosophy that underground space must support life above ground.
