Also worth noting: "modern" dwellings not necessarily can be traced back to still existing "primitive" ones.
Also worth pointing out the obvious: building materials had to be available first. So before felt existed they couldn't use that as building material, but animal skin, or tree bark, both material behaving a bit differently than felt. Or some wood types are better suited for banding than others, that had to be available in relatively nearby for large scale use - climate changes changed the vegetation cover through the millennias.
