Architectural and Artistic Research (AAR) is a specialized process that provides an in-depth understanding of a building’s architectural, historical, and artistic value. AAR is carried out during the design phase as well as throughout construction and restoration works. The research includes analysis of building structures, finishing layers, decorative elements, and spatial composition. Historical construction stages, alterations, and authentic materials are identified and documented. AAR is particularly important for heritage buildings and listed monuments. Research findings serve as a foundation for informed design and restoration decisions. The process often involves probes, surveys, measurements, and photographic documentation. AAR helps preserve authenticity and prevents irreversible damage. This approach supports a balanced integration of modern use with historical value preservation.
