This thesis explores sustainable strategies for urban regeneration through the adaptive reuse and partial reconstruction of the Ex-Perotti military barracks in Bologna. The research originates from the C40 Cities Student Housing Competition[1], which served as the conceptual framework and provided the site context and design objectives for the project. The competition’s focus on affordability, sustainability, and inclusive community development inspired the academic exploration of how these principles can be translated into a feasible architectural proposal that meets real-world urban needs. While the competition offered a starting point, the work was developed independently as a comprehensive academic study that combines design innovation with analytical evaluation.
