| Dwelling | Details |

| Yurt | Dwellings made of animal skins • Steppe Region |
| Kraal | Grass dwellings of Bantu and Zulu (Africa) |
| Igloo | Dome-shaped snow houses of the Eskimo race |
| Aoul | Tent-like dwelling (Caucasus region – Europe/Asia border) |

Igloo = Ice/Snow (Arctic) · Yurt = Animal skin (Steppe) · Kraal = Grass (Africa) — dwelling material always matches the local climate and available resources.
