This must have been the default for human history probably as well, I am thinking.

Personally, I sleep better when I’m alone. Haven’t convinced my wife that we should have a separate king and queen suite, though.
There are still a few that live traditionally in what basically is a large, two-floor long house for a multi-generational household. The families live on the second floor in one large room, but often with a small loft area for a quasi-third floodr The bottom floor is open with no walls (just support beams) to keep the animals. So it's constantly noisy.
