A masterpiece of the Leningrad school of constructivism – House of Culture named after Ilyich (Cultural and leisure center «Moscowsky»)

Architects of the 1920–1930s acted in the context of the new communist agenda, constructing the spatial environment of the person of the future. The projects of that era realized a dialectical connection between formality (geometricity) and functionality (utilitarianism). Constructivism became the key style of this stage; he was characterized by experiments with volumes, rectangular and curvilinear shapes. House of Culture named after Ilyich, which is the focus of this study, became one of the signs of the time — the era of palaces and houses of culture, where cinemas, concerts, sports, rehearsal halls, libraries, music schools, premises for clubs and circles were located under one roof. The article presents an analysis of the volumetric-spatial solution, the functional characteristics of the building and the history of the existence of the building of the House of Culture, and also identifies the problem of the preservation and restoration of constructivist architecture. In 2020, the House of Culture named after. Ilyich received the status of an object of cultural heritage of the Russian Federation of regional significance. The analysis of the scientific context makes it possible to conclude that today in the scientific community there is an increased attention to avant-garde architecture as a striking phenomenon of Russian architecture and a change in the protective status of the House of Culture building is a positive marker of a change in attitude towards the architecture of the 1920–1930s.
