The article deals with the situation of paradoxical, at first glance, the formation of Art Deco, which was bourgeois in origin, in Soviet architecture. It is in Art Deco that the symbiosis of the achievements of historicism of the bygone century, Art Nouveau, neoclassicism, cubism, European functionalism and Russian constructivism will take place, which will be embodied with all the variety of influences into an organic unity of form - into the style of the interwar decades. The features of Art Deco in its regional version are analyzed on the examples of multi-apartment residential buildings, a workers' club, a cinema. The emergence of Art Deco in Soviet architecture was due to close acquaintance with European artistic practice, the presence of Russian architects and artists at the International Exhibition of Modern Decorative and Industrial Arts in Paris in 1925, the desire for new forms of organizing everyday life, a new understanding of comfort and relaxation, a new pastime - visiting cinemas, traveling, sports. All these innovations could not but be visualized in various types of art, and, of course, in architectural solutions. The manifestations of the Soviet Art Deco as one of the stylistic trends in the architecture of Omsk in the 1920s - late 1930s, formed on the basis of the evolution of late modernism, neoclassical trends and constructivism, are concretized. The local features of the Omsk theme of "regional Art Deco" of the 1920s-1930s include a slight tendency to ornamentation, the absence of plastic brightness of details, the stability of the constructivist tradition, which is manifested in general in the appearance of buildings; to the general tradition of the stylistic wave - rationality and geometricity, retrospectiveness and at the same time the desire for novelty and comfort. At the same time, we can talk about the presence of theatrical effects in the architectural decoration of the facades of Omsk buildings, and the sound of the Egyptian theme, and the citation of neo-Renaissance motifs. It is noted that the experience of Art Deco will subsequently find its application in Soviet architecture, when these stylistic qualities and solutions are required in order to color the architecture of Soviet cities during the period of directive minimalism of the 60-70s of the last twentieth century.
