MALAKHOV Sergey A. 69-74 p.

Based on the research of humanitarian specifics of architectural form and architectural objects, three aspects are defined, from the position of which the CM system is adjusted the concept of the architectural object as megaobject (interconnected system of object and the physical environment) and how metaobject conditioning facility, cultural space). The first aspect – the role of the binary opposition, meaning that in the architectural form of the object and system identification, or in a non-obvious, presented meanings that oppose each other, but do not displace each other. The second aspect – the presence of “external environment” (URBO landscape and cultural space). The presence of the environment, the environment has a formal aesthetic and ethical justification. As a result, the environment may become a challenge no less important than the object. The third aspect – the fundamental metavalue of architectural object, the method adopted in the composite as a basis. It relates to the interaction between the city and the house – two metavaluesi, covering almost all the layers and subsystems which appear in the process of interaction between the author and architectural form. This fundamental aspect is defined in the article as a universal binary formula “House-City.” The binary formula “HouseCity” determines the methodological structure and content of the genesis of the CM process carried out in phases as a gradual transition from the experience of abstract form to the project.
