Stalinist architectural style.
The style is much harder to define on an individual building scale unless your focus is one of the state buildings or the Soviet Academy of Architecture. Mostly it shows on an urban planning scale. Long parklike boulevards lined with housing blocks ending in huge plazas and major monuments or buildings at the ends of boulevard views.
Building exteriors used a lot of brick, terra cotta or unit concrete over nearly any kind of structural system. A lot of small windows. Imagine everyone placing a brick to build each building and enough windows so everyone got a window. This was the triumph of the common man, all of which are equal. Every element was to showcase the new social order of the many coming together to create greatness and every view to show the monuments the new order had accomplished.
But, outside the grand streets communism showed itself as massive project-like housing structures. The masses in cities were to work in factories, and factory-like construction was used to house them.
The large city centers were used as propaganda to the state that looked like modern classical buildings towering into the sky. Everywhere else was brutal mass-produced buildings that went on as far as the eye can see.
