We adopt a multidisciplinary approach based on scientific conservation principles in the restoration of historical palace structures. The process begins with the preparation of survey, restitution, and restoration projects and continues with interventions compatible with the original materials, construction techniques, and architectural character of the buildings. Stone, wood, marble, plaster, and decorative elements are strengthened through laboratory analyses and conservation methods, while structural problems are resolved through engineering solutions. Cleaning, consolidation, repair, and completion works are carried out with respect for the original fabric and without compromising the historical identity of the structure. Through this holistic restoration approach, the architectural, cultural, and aesthetic values of palace buildings are preserved, and the structures are transferred to future generations in a safe, sustainable, and authentic manner.
