The educational convention center in Tres Rios, Phoenix, Arizona, includes offices, exhibition space, a convention center, multi-use classrooms, and a FEMA disaster center with short-term housing for climate emergencies. Designed to immerse visitors in the processes of water treatment and the Tres Rios Wetland, the center fosters an understanding of sustainable water management. Positioned between the wetland and a restricted water treatment facility, it bridges the gap by making these essential but inaccessible systems visible and engaging. The concept of ‘in-between’ shapes the design, reflecting the site’s role as a transition between urban and natural environments. A square structure anchors the center, with diagonal pathways that guide visitors through exhibitions, symbolizing the flow of water and creating a direct connection between the architecture and its purpose. By combining educational spaces, exhibits, and outdoor areas, the center provides a platform to explore the ecological value of wetlands and the importance of conservation.
