Are there any other type of houses beside igloo that is found in the north frigid zone?

Yes, besides igloos, there are several other types of houses found in the northern frigid zone. These include traditional structures like the "yurt," used by some Arctic nomadic cultures, and "tents" made from animal skins, which are portable and suited for the harsh environment. Additionally, some Indigenous peoples build semi-subterranean homes, which help insulate against extreme cold. Modern adaptations also include insulated cabins and structures designed to withstand severe weather conditions.
