Ecotone is a transformative adaptive reuse proposal that reimagines an abandoned school as an urban ecological center and public park. Rooted in sustainability and community engagement, the design bridges the built and natural environment—an "ecotone" where people, nature, and education intersect. By preserving the existing structure and layering new ecological functions, the project creates spaces for environmental learning, social gathering, and ecological restoration. It honors the site's past while positioning it as a catalyst for a more resilient and connected urban future.
