The first number opened by the competitive project of the building of the Moscow branch of the newspaper Leningrad Pravda (1924, architect. vesnins brothers).

1926 WASP was in acute controversy with ASNOVA on the main issues of architectural creativity. OSA was criticized for formalism ASNOVA; the members of the Association objected to the separation of architectural issues from utilitarian needs; sought to the emotional impact of the new architecture through a system of building new social structures, the highest quality all of its parts, the interaction of the architectural elements (plane, volume, spatial relationships, scale, texture, color). In turn ASNOVA criticized the OCA for underestimating the values of architectural forms.

the members of the OCA was engaged inactive architectural practice, both independently and as a team. Created such software projects as: the Institute of library science to them. V. I. Lenin on Lenin hills (1927, architect. I. I. Leonidov), Planetarium (1927, architect. M. O. bars, M. I. Sinyavsky), the Narkomfin Building (1928, architect. , Ginzburg, I. F.

Since the early 1930-х OSA has been criticized. In particular, P. Osipov in the magazine "art to the masses," wrote: "Denying the value and role of art as an ideological factor, the constructivists falling into the camp of our enemies and unknowingly contribute to them... Replacing the architecture, engineering, OSA brings the importance of architecture as a field is narrow-идеологической, to the beauty, the slogan of which is @ldquo;смерть искусству...” Summing up the work of the constructivists in contemporary architecture, it should be said that if the technology field they have great services (new material, standardization, typification, etc.) ideologically it is a solid individualism and the dominance of technicism over art... our constructivists, despite their formal and technical achievements, still largely following in the footsteps of their Western counterparts and are almost indistinguishable from the last. And espouse the only difference is that they are building a house-коммуны, and Western — mansions, is extremely unconvincing, as constructivists of our move abroad, they will feel the same way as West, and also would build houses and individual apartments according to the taste of the bourgeoisie".

In 1932 the activities of the Association ceased on the decision of the Central Committee of the CPSU (b) "On restructuring literary-художественных organizations."
