The project addresses the challenge of reconnecting a fragmented metropolitan site shaped by infrastructural barriers, contrasting urban scales, and isolated development zones. Elevated railway plots, vehicular spines, and disconnected circulation networks create conditions of spatial separation that limit accessibility and urban continuity across the district. In response, the masterplan is organized into five interconnected urban units linked through bicycle infrastructure, pedestrian bridges, landscape corridors, and layered circulation systems. Each district develops a distinct spatial and programmatic identity while remaining integrated within the larger urban framework. The Commercial Triangle, The Arcade, Bercy Arena, The Twisting Bridge, and The Tower District combine public programs, mixed-use development, and open landscapes through porous architectural configurations that allow movement, visibility, and interaction between buildings, infrastructure, and public space. Rather than following rigid zoning principles, the project distributes cultural, commercial, recreational, residential, and professional programs across the site to form a continuous public environment capable of supporting diverse forms of urban life.
