Please be honest, the vast majority Russians and other Soviets didn't live in communal apartments for the past 60 years. Not only did they have access to new construction commie blocks (small and ugly, but warm and well connected), well over 50% of them had summer homes (datchas) and many still do today.

Anyways, you're missing my point. Which was to solve the post-war housing crisis by building up with prefabs. And it worked - rapidly.
