The article examines the stability of the volumetric composition of architectural monuments as a key condition for their long-term preservation in the context of contemporary environmental, technological, and socio-cultural challenges. The author substantiates the need for a comprehensive approach to the preservation of Kazakhstan's cultural heritage, including a systematic survey of objects using engineering, geological, climatic and digital diagnostic methods.The scientific novelty of the work lies in clarifying the role of architectural and spatial sustainability as an integral indicator of the preservation of monuments, as well as in identifying the relationship between structural stability, adaptive functional use and the preservation of historical authenticity. The study shows that effective preservation of architectural objects is possible when traditional restoration practices are combined with modern monitoring and digital modelling technologies, as well as when adaptive use strategies are implemented to ensure the integration of monuments into the modern urban environment without losing their cultural value.The proposed approaches can serve as a methodological basis for the development of sustainable strategies for the preservation of the region's architectural heritage.
