Abstract: Within the framework of this article, constructivism is viewed not only as a phenomenon of Russian culture, but also as an important segment of architectural heritage. The authors analyze the prerequisite for origination of such art style along with specificity of its implementation in one of the Siberian largest cities – Omsk. Following the logics of covering the topic at hand, the author gives characteristics to the key aesthetic and constructive innovations of constructivism, its contribution into the development of architectural theory and practice, focusing attention on the peculiarities and factors of realization of the national trends in the context of the actual local space of a Siberian city. The authors underline the need for acknowledging the importance of constructivism’s legacy as a segment of architectural heritage. The research results allow assessing the characteristic and relevance of constructivism as a segment of architectural heritage, which is directly associated with the specificity of historical situation established in Russia within the post-revolutionary period. At this time, the buildings belonging to this art style are clearly underestimated, which is why many of them are still not protected as historical landmarks and are subject to reconstruction.
