It seems that one of Rodchenko’s (many) gifts was his ability to conceptualize with a sense that his structures could vary greatly in their size. From some of the photographs, it becomes an optical trick to determine how big a structure actually is.
I was reminded especially of artists like Mark di Suvero’s works at the Storm King art center in mountainville, ny. You get a sense of this idea scale in great effect; in an expansive outdoor space you can view structures from so far away that they are almost like toys, but you also can interact with them in their monumental reality.
