Morphological and structural-compositional features of the historical block development of St. Petersburg

The development of the historical center of St. Petersburg has special parameters and characteristics that form the uniqueness of the city as a whole and its individual fragments. At the moment, due to the emerging urban planning errors and violations, there is a need to clarify the strategy of urban planning regulation of the historical center in order to preserve the uniqueness, integrity and quality of its architectural and urban environment. In this regard, the task of moving to a detailed and comprehensive study of the parameters of fragments of the urban environment becomes urgent. The purpose of this study is to study the existing architectural and urban planning characteristics of the residential development of St. Petersburg. The object of research is the historical block within the boundaries of Moskovsky Prospekt, Klinsky Prospekt, Bronnitskaya Street, Zagorodny Prospekt. The subject of the study is morphological and structural-compositional features of the building. On the basis of the conducted historical, archival and bibliographic surveys and a full-scale survey, the enlarged stages of the formation of the block were identified and the main patterns of the construction of the front front were determined. The morphotype of the block is a perimeter building of the historical center of St. Petersburg of the XIX century with the inclusion of objects of the mid–XX century, with irregular surveying and an incomplete system of courtyard buildings. The nature of surveying and urban fabric, which developed mainly in the second half of the XIX – mid XX century, was influenced by the planning structure laid down in the XVIII century and the location of the block in the structure of the city. The compositional organization of the front along Moskovsky Prospekt is subject to uniform principles, which made it possible to form a high-quality urban environment. The front facades have fragmentary losses of decorative elements and structural violations at the ground floor level, which can be eliminated provided that the historical rules of formation and decorative and plastic design of buildings are observed.
