These second-level subsystems are in turn divided into indivisible elements. The structural model of the architectural-planning system, depending on the functional purpose of the structure, is divided into main components, which are the basis of the functional-planning organization of the building, which should correspond to the main processes (rituals, rituals) for which the structure is designed. 2.
