 Lissitzky , aware of severe mismatch between his ideas and the existing urban landscape , experimented with different configurations of the horizontal surface and height @-@ to @-@ width ratios so that the structure appeared balanced visually ( " spatial balance is in the contrast of vertical and horizontal tensions " ) . The raised platform was shaped in a way that each of its four facets looked distinctly different . Each tower faced the Kremlin with the same facet , providing a pointing arrow to pedestrians on the streets . All eight buildings were planned identically , so Lissitzky proposed color @-@ coding them for easier orientation .
