Soviet housing buildup was not a complete failure. That's an absurd thing to claim. It was maybe one of the best most successful program in the Soviet Union.

The Soviets had critical housing shortage after the Civil war and even worse after WW2. And even those houses that existed were pre-WW1 standards of modernity.

Now I think a to strong embrace of modernism. A lack of small scale capitalism. And their hatred for pre-Soviet old town really hurt them. And eventually to much copying the US in terms of cars did hurt their program.

But saying its a failure is simply inaccurate. From 60-80 an absurd amount of modern housing was built.
