This article examines the architectural and spatial organization of a pedestrian street, presented as an object in the form of a multifunctional complex. The subject of the study is the architectural and typological features of the components of a multifunctional pedestrian street. The novelty of the approach lies in the representation of the street as an integral object in the form of a multifunctional complex in the structure of the residential quarter of St. Petersburg. The article also contains a systematic analysis of architectural planning, urban planning and compositional solutions for objects of this type. The analysis is based on combining the principle of operation of a pedestrian street with the criteria of multifunctionality. The main section of this study is devoted to an overview of the structure of diversified objects included in the pedestrian street building. The scientific novelty of the work consists in considering a pedestrian street as an independent object in the form of a multifunctional complex incorporated into the structure of a residential quarter. For this purpose, the project "Multifunctional Street in the structure of the Lenexpo quarter" (St. Petersburg) was carried out by the Bachelor of Architecture Peter Dmitrievich Cherepanov under the guidance of Konstantin Ivanovich Kolodin, Associate Professor of the Department of Architectural Design of the St. Petersburg State University of Architecture and Civil Engineering (SPbGASU). On the basis of the completed project, a typology of objects combined into a multifunctional complex was formulated. The project was developed taking into account the multisectoral unification, as well as taking into account the principles of modular structuring of space and the construction of individual buildings and structures. The mechanism of the pedestrian street operation was calculated, which was reflected in architectural planning and spatial solutions when designing this complex. According to the content of the main sections of the study, conclusions were formulated that take into account the prospects for the development of such architectural objects in the future.

The lack of recommendations for establishment of a sustainable architectural environment at Lake Baikal predetermines a haphazard approach to territory development. The growing tourist flow increases anthropogenic environmental loads. These issues require the development of the necessary architectural tools for the implementation of local projects. The article focuses on the particular properties of the spatial solutions for detached houses with public functions.

The article reviews one of the types of ecological tourism – ecological settlement, its history, advantages and disadvantages. The domestic experience of ecological settlement engineering according to the criteria was analyzed, as well as the experience of existing settlements in the Baikal Natural Territory. The generally accepted scheme of ecological settlement arrangement cannot be implemented in its original form, since each site has its own features. Lake Baikal and its adjacent territories are UNESCO sites, have difficult climatic, geomorphological, landscape conditions, etc. The relevance of ecological settlement arrangement in this territory has been proved. As a result of the analyzes, a scheme of ecological settlement arrangement in the BNT was created. The results obtained allow us to conclude that it is possible to expand the field of research and search for new models. Cluster-based ecological settlements can serve as one of the directions for development. However, one of the most effective ways to check the results is the actual ecological settlement arrangement in the BNT with subsequent study during construction and operation.
