The OSA Group (Organization of Contemporary Architects) was an architectural association in the Soviet Union, which was active from 1925 to 1930 and considered the first group of constructivist architects. It published the journal SA (Sovremmennaia Arkhitektura or 'Contemporary Architecture'). It published material by Soviet and overseas contributors. However this led to them being attacked as a 'Western' group and some individuals as being 'bourgeois'. After the closure of the group, their modernist approach to architecture and town planning was eliminated in the Soviet Union by 1934, in favour of social realism.
Contemporary architecture
Like the ASNOVA group, OSA grew out of the avant-garde wing of the VKhUTEMAS school in Moscow. The group's founders were Moisei Ginzburg, well known for his book Style and Epoch (a Soviet response to Le Corbusier's Vers une Architecture) and the painter, designer and architect Alexander Vesnin. Unlike the earlier association the OSA group claimed for itself the name Constructivist, in that it was, in its utilitarianism and concentration on function rather than form, an architectural equivalent to the experiments of 'artistic' Constructivism. OSA was in many ways the architectural wing of the socialist Modernists of LEF, and likewise set up its own journal in 1926.
Until its closure in 1930, SA would publish articles on a variety of subjects, including a symposium on flat roofs, a special issue on colour in architecture, and discussions of Le Corbusier, the Bauhaus, Fernand Léger, and Kasimir Malevich (who was also a contributor to the journal). The design was mainly by Aleksei Gan, who also designed the distinctive grid pattern of the covers. Photography was occasionally by Alexander Rodchenko. As well as publishing on the built projects of Modernism, the journal published experimental projects by VKhUTEMAS students such as Lydia Komarova's Comintern project, the strange pod houses of Sokolov, and the works of Ivan Leonidov. Articles in the journal was mainly in Russian, though occasionally parts of it were in German, highlighting the group's affinities with the Neues Bauen, although no OSA architects were invited to contribute to the Weissenhof Estate. The group was, however, the Soviet counterpart of Der Ring in Germany: agitating for Modern architecture and construction methods, and polemicising against the Classicism and Eclecticism that would eventually coalesce into Stalinist architecture.
OSA activities
There are several examples of built works designed by OSA members in the USSR. These include Moisei Ginzburg's apartment blocks (on Gogolsky Boulevard, Moscow, another in Sverdlovsk, and most famously the Gostrakh and Narkomfin buildings); the 1920s-'30s work of the Vesnin brothers such as the Likhachev Palace of Culture and the Mostorg department store in Moscow, and the Ivanovo bank and DneproGES power station; works by Mikhail Barsch, such as Moscow Planetarium (with Sinyakvsky) and the Gostorg office block (as part of a team headed by Boris Velikovsky); works by Ivan Nikolaev, such as the electrical-technical complex in Moscow (with Fissenko; this work was featured in MOMA's 1932 International Style exhibition) and the large collective house for the students in Moscow; and the workers' housing designed by Alexander Nikolsky in Tractor Street, Leningrad.
The OSA group's leading theorists were members of the CIAM from 1928 until 1933, with Ginzburg and Nikolai Kolli members of its secretariat, CIRPAC. A small CIAM meeting with the OSA group was held in Moscow in 1932, with Sigfried Giedion and Cornelius van Eesteren in attendance. Sergei Eisenstein's The General Line featured specially built buildings by OSA's Andrey Burov. The utopian projects of Ivan Leonidov were first published in SA, and their technologically advanced, fantastic nature led to harsh criticisms from the VOPRA group of Arkady Mordvinov and Karo Alabian, coining the phrase 'Leonidovism' to attack this 'Western' group: in a 1929 editorial SA trenchantly defended Leonidov, but this was a sign of what was to come, with Mikhail Barsch being targeted in an 'anti-bourgeois' campaign at VKhUTEMAS/VKhUTEIN.
