Soviet industrial architecture projects by Nikolay Boykov from the early 20th century

The article aims to study partially or completely lost industrial facilities designed by Nikolay Boykov and built in the 1920s in the Irkutsk Region that represent historical, cultural, and architectural value. In the work, such methods as retrospective analysis, historical reconstruction, and cluster analysis were used. The retrospective analysis was applied to study the territories of industrial facilities, which were occupied by some structures prior to Nikolay Boykov’s involvement; the architect’s contribution to the construction of new buildings and reconstruction of existing structures was ascertained; the design and construction time frames of Nikolay Boykov’s projects were revised. The cluster analysis revealed some quantitative and qualitative characteristics of three main industrial facilities that were designed by the architect under the conditions of modernization and new construction. The study of the years of Boykov’s activity revealed stages in the construction and reconstruction of industrial facilities (“Sibiromongol” leather factory, CPS-2, and Khaitinsky porcelain factory), and identified buildings that were most likely to have been designed with his involvement. The present author used archival documents and open sources to reconstruct and prepare layout plans of workshops at the “Sibiromongol” leather factory and Khaitinsky porcelain factory during the years of Boykov’s activity. The study of these facilities showed the value of the considered projects, the necessity of preserving the deteriorating structures that constitute a stratum of cultural, architectural, and historical development of industrial facilities from the early 20th century in Russia.
