I loved this article from The Awl on some of the more outlandish examples of Soviet era architecture:
The 1975 Soviet film The Irony of Fate, a Russian favorite for Christmas season viewing to this day, boasts a Twelfth Night-like plot that turns on the anodyne similarity of Soviet housing. The narrator opens, mordantly, “In the past when people found themselves in a strange city they felt lost and lonely. Everything around was different: streets and buildings, even life. But now it has changed. A person comes to another city and feels at home there.” In a landscape of bland uniformity, “can you name a city that hasn’t got First Garden Street, Second Suburban Street, Third Factory Street, First Park Street? Second Industrial Street, Third Builders Street?” This similarity in design, not to mention the standardization of furniture and locks, results in our drunken protagonist deposited in the right apartment on “Third Builders Street”, but in the wrong city, and romantic comedy misadventures follow. (In fairness, It’s a Wonderful Life must look like a pretty odd holiday ritual to the average resident of Novosibirsk as well.) In any case, there’s no denying that most Soviet construction was oppressively dull and derivative; in this case, Soviet censors didn’t even seem to bother to try.
