Changchun as a modern city grew during the construction of the Chinese Eastern Railway and South Manchurian Railway. The article discusses the interaction and interpenetration of different cultures on the example of the architectural development of the city of Changchun from the late 19th to the first half of the 20th century. This period encompasses two key stages of urban development: the initial period and the period of the South Manchurian Railway. The article gives examples of the most typical samples of the architectural style of the period. The study of the development of architecture in Changchun City and its comparison with other major cities (Shenyang and Harbin) of Northeast China of that time shows that in the process of development Changchun city has changed its architectural style. This occurred under the influence of traditional Chinese, Russian, and later — Japanese architecture.
In the 20th century Japanese house has undergone a tremendous metamorphosis transforming from established vernacular typology to a vast range of different architectural approaches. This process took form of complex interaction between Japanese vernacular and new western dwelling. The purpose of this research is to identify the origins for the space organisation of contemporary Japanese house. This has been done by examining three houses of architects A. Raymond (1926), K. Tsuchiura (1935), and R. Maekawa (1942) with a focus on correlation between architectural space and social meaning of dwelling space in Japanese tradition.
