Urban specificity of the first square in Samara (XVI- middle XIX centuries)

VOSTRIKOV Vladimir 63-68 p.

The paper goes into the questions connected with the creation and further evolution of the first square of Samara in the XVI-XIX centuries. The article analyses historical formation of the square territory taking into account the main buildings construction, as well as its role in the development of other areas. The authors describe basic stylistic and functional characteristic features of this area and identify its typology and planning decisions with account of the structure of urban neighborhoods. The paper shows that the first confirmed plans of changes affected this important hub in the historic center, where traditionally the main place was given to the churches – the main Orthodox shrines of the city. Various political as well as economical and technical factors played an important role in the transformation of the square. It allowed to design and create a number of extraordinary objects but still led to only partial realization. On the one hand, ongoing construction in the XIX century in Samara has shown a formal commitment to follow the requirements of classicism. On the other hand, it heralded the era of eclecticism with a significant rethinking of architectural-artistic image in the shared spatial system of the city.

Binary formula “Home-city” as metavalue of arcitectural object and a binaty oppositions matrix of compositional techniques

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.
