Historic buildings, often located in city centers, frequently become unused or underutilized spaces. Their rehabilitation, through reconstruction or preservation, presents a significant opportunity for sustainable urban development. Adaptive reuse not only revitalizes these structures but also offers social and cultural benefits, ensuring their preservation for future generations. This study aims to emphasize the importance of adaptive reuse as a sustainable approach to construction and urban development. A qualitative research methodology is employed, incorporating a review of related literature and an analysis of European case studies showcasing adaptive reuse projects. The findings highlight the pivotal role of adaptive reuse in sustainable development by preserving historic architecture, reducing environmental impact, and fostering cultural continuity. By analyzing several adaptation examples, the study underscores adaptive reuse as an essential strategy for balancing heritage conservation with modern development needs.
