I can give several examples of what I think were the connective tissue of the neighborhood: We had an awesome food cooperative https://www.foodcoop.com/, a playground, a fro-yo place with outdoor seating, a YMCA, and numerous cafes. These days there is a recreation center.
Now, there is a different problem -- housing is expensive. When you have a huge mortgage, you spend more time at work, more time worrying about work, and less time enjoying life. That isnt the fault of the buildings, it is more about restrictive housing policy and multi-decade-ZIRP.
(To be fair, the noise was always an issue, and in my current place, it feels really nice to be able to do jumping jacks and play the piano at 9pm. So there's that.)
But yeah when I was in LA and had to start going to therapy because the neighbors in our orwellian apartment building were making so much noise I was having week-long panic attacks the therapist told me he grew up in S.Korea and people would stab their neighbors over noise regularly.
He was a great guy but that was kind of his only advice? That stuck with me.
A sad state of affairs.
You can compare the relative success of low-income low-rise developments vs. the notorious high-rise projects that were universal failures
In that building there were two elevators - one "normal" for US standards and one oversized, presumably for moving.
I don't think it's unreasonable to have such a setup for a large building, particularly with how large furniture and beds can be.
It mainly had to do with being "disconnected" with the street once you were more than 5 floors up if I remember correctly.
