In recent decades, there has been a steady trend in architecture toward the adaptive reuse of historical buildings, which holds not only practical but also cultural value. Renovating old buildings for new purposes has become an essential part of urban planning, addressing both contemporary challenges and the need to preserve architectural heritage. With advancements in medicine and veterinary technologies, there is an increasing demand for functional, safe, and modern facilities. This often prompts architects and designers to seek innovative solutions for transforming historical structures. This practice is neither exclusive nor unique. On the contrary, it is a fairly widespread process that allows for the preservation of historically significant buildings, breathing new life into them and integrating them into the modern urban landscape. A key aspect of this approach is the use of eco-friendly and smart materials, which not only enhance the functionality and energy efficiency of buildings but also meet modern safety and sustainability requirements. Restoration of such objects not only helps preserve unique historical heritage but also creates comfortable conditions for new purposes. This process ensures the preservation of historical architecture while giving it a new role and relevance. This article explores the key aspects of this approach, including the use of eco-friendly and innovative materials that support the health of both animals and humans, while contributing to the creation of sustainable and comfortable spaces in historical buildings.
