Location for the Pravda-building Moscow (Competition 1924 (Vesnin/Melnikov))

[Bitnik]

Hello,

I hope someone can help!
There are many informations about the competition for the Pravda-building in Moscow 1924. Two of the projects are even very famous: The design of Vesnin and the one of Melnikov.
But there is so difficult to find something about the proposed site for the building. The only informations we could gather was that it was planned for the Strastnaya Square (today Pushkin Square) and that the plot was 6 x 6 m.
We didn´t find further informations, about the position of this plot inside the square: Neither a site-plan nor scribbles or similar...
Perhaps someone of you have more informations about the planned location for this building in the competition? It would be fantastic!
Thank you very much in advance,
Arturo
