 Although the Vesnin brothers won the contract to produce working drawings, they were forced to share control with Arkady Mordvinov and his VOPRA associates, harsh critics of the OSA Group and other established architects.Friction among the "team" delayed construction for years; the project was abandoned when the capital of Ukraine relocated from Kharkiv to Kiev.The first public constructivist building actually built in Moscow by the Vesnin brothers, a 1927 department store in Presnensky District, was a scaled-down clone of their 1925 TsUM department store draft.
