Not ancient, but I come from indigenous folks that live Southeast Asia. Because we're from up high in the mountains, the traditional way of living is supposed to go back quite far in time.

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.
