Abstract: The work presents a systematic picture of the development of the historical core of the architectural ensemble of the central main street of the city of Khabarovsk – Muravyov-Amursky, which was formed during the second half of the 19th – early 20th centuries, and is currently of absolute interest from the point of view of studying the history of regional architecture of the pre-revolutionary period associated with the economic development of the eastern outskirts of the Russian Empire, the construction of new cities and settlements and the creation of transport infrastructure that connected the Pacific region with the central part of the country.
The study was based on materials obtained by the authors during the study of scientific and local history literature, Internet resources and archival searches, as well as their own field surveys of street development.
As a result, the stylistic and space-planning characteristics of the buildings and structures included in the ensemble, determined by the specifics of the development of the city and its architectural and construction complex, were considered. The study showed that the status of Khabarovsk as the administrative center of the Amur Governor-General and, as a consequence, the presence in it of three categories of customers: the city administration, the military department and private merchants, as well as the characteristics of local building materials, determined the typological and form-creative diversity of the ensemble of the central street of the city , which developed during the period under review in four stylistic systems: Russian style, retrospectivism, “brick” style and modernism.
The authors identified a range of problems of interaction between historical buildings and new construction objects, which are actively being introduced into the urban fabric and changing the perception of the cultural landscape of the city.

Abstract: The article reflects the intermediate results of a study conducted within the framework of the scientific project "Architects and engineers of the eastern outskirts of Russia (second half of the 19th - early 20th century)". Within the framework of this publication, the authors raise the question of the need to study and comprehend the unique layer of regional architecture - the preserved wooden buildings of the capital of the Trans-Baikal Territory, the city of Chita. Based on data from field surveys, the study of scientific literature and Internet resources, as well as data obtained in the course of work in the State Archives of the Trans-Baikal Territory, a systematic picture of the historical evolution of the wooden building of the city from the moment it was founded to the events of the October Revolution and the Civil War is presented for the first time.
Particular attention is paid to the problems of developing the planning structure of the city and the ratio of wooden and stone buildings at different stages of its development. The features of the space-planning organization of buildings and structures of various typologies, the transformation of methods of decorative design of street facades and their dependence on the location of objects in the structure of the urban fabric are considered. Data are given on the creative and professional activities of a number of architects, engineers and other masters of architectural and construction art who worked in Chita in the period under review and who had a significant impact on the formation and development of the city's wooden buildings, as well as the spread of various architectural styles.

Abstract: The article presents the results of a study conducted by the authors with the support of the Russian Science Foundation grant "Architects and engineers of the eastern outskirts of Russia (second half of the 19th - early 20th centuries)". The features of a significant layer of regional wooden architecture, preserved in the capital of the Trans-Baikal Territory - the city of Chita, are considered. Based on the materials of field surveys and the State Archives of the Trans-Baikal Territory, the preserved objects and original designs of a number of buildings and structures for various purposes were studied. The wooden architecture of the city is viewed through the prism of the activities of the first city architects and engineers, as well as other masters of the building art who received professional education in the leading architectural and engineering schools of central Russia, as well as specialists who did not have a specialized education, but received the right to carry out architectural and construction work after passing exams at the Ministry of Construction Affairs in St. Petersburg. As a result, a complete systematized picture of the historical evolution of the wooden architecture of Chita was compiled, which was formed under the influence of all-Russian architectural traditions, but at the same time had its own distinctive features associated with the specifics of the development of the region and the personal ideas of the masters of architectural and construction art, as well as customers of architecture of this type.

Abstract: This article presents the materials of the research conducted by the author within the framework of the scientific project “Architects and Engineers of the Eastern Suburbs of Russia” (late XIX – early XX century)". The paper touches upon the spheres and results of activity of the graduates of Saint Petersburg Institute of Civil Engineering, who worked in Yakutsk in the pre-October period. Brief biographical records are provided on the following civil engineers: A. N. Aristov, N. V. Baumgarten, G. F. Katsienko, A. I. Kudryavtsev, K. A. Leshevich, G. V. Rozen, I. F. Tamulevich, and V. A. Shkalin. The significance of the preserved objects of artistic heritage of the graduates of Saint Petersburg Institute of Civil Engineering in the site development of the historical core of Yakutsk is described. Based on the field surveys and archival findings, the author presents the holistic picture of creative and professional activity of the graduates of Saint Petersburg Institute of Civil Engineering who worked in Yakutsk in the late XIX – early XX centuries. It is established that the administrative, urban planning and creative activity of civil engineers associated with routine work in the local government  bodies, coordination and planning of the projects of facilities of various purposes, had a considerable impact upon the development of regional architecture, and as well as new construction technologies of the large public buildings in the conditions of permafrost.
