De Blue is a vision for the adaptive transformation of Jamsu Bridge, reimagining it not merely as infrastructure, but as a living urban system. Situated on the flood-prone Hangang River in Seoul, the project integrates architectural, landscape, and environmental strategies to convert the bridge into a multi-dimensional spine of everyday and seasonal urban life. The design introduces a “365-Day Cycle of Activity,” offering flood-resilient pathways, floating parks, aquatic museums, sports facilities, and cultural gardens that can function throughout the year, regardless of climate conditions.

The project is rooted in the principle of Spontaneous Symbiosis: rather than forcing adaptation upon people, it proposes infrastructure that organically evolves with urban phenomena and climate shifts. Through modular zones, vertical access towers, energy systems, and nature-based water filtration, De Blue not only supports mobility and recreation, but also generates clean water, air, and new social ecosystems. It redefines the role of infrastructure in the 21st century as resilient, inclusive, and regenerative.
