The paper is devoted to the improvement of the modern methodological apparatus for describing and modeling the structure of architectural objects, which is focused on current trends in the design of buildings and structures with a certain degree of variability and adaptability to rapidly changing modern requirements of potential and real users and external environmental conditions (natural, man-made). In addition, the complexity and variability of the structure of architectural objects directly affect the increase in their operational characteristics, the improvement of security systems and the hierarchy of structures of spaces of different access levels. Another aspect of this problem is the creation of a scientific basis for the formation of a more flexible regulatory framework in architecture.
