Modern tree houses may also be integrated into existing hotel facilities.Īlong with subterranean and ground level houses, tree houses are an option for building eco-friendly houses in remote forest areas, because they do not require a clearing of a certain area of forest. Modern tree houses are usually built as a hut for children or for leisure purposes. The Korowai, a Papuan tribe in the southeast of Irian Jaya, live in tree houses, some nearly 40 metres (130 ft) high, as protection against a tribe of neighbouring head-hunters, the Citak. In some parts of the tropics, houses are either fastened to trees or elevated on stilts to keep the living quarters above the ground to protect occupants and stored food from scavenging animals. Įven today, treehouses are built by some indigenous people in order to escape the danger and adversity on the ground. This has led to a hypothesis that archaic humans may have lived in trees until about 40000 years ago. However, evidence for cave accommodation, terrestrial man-made rock shelters, and bonfires should be possible to find if they had existed, but are scarce from earlier than 40000 years ago.

It is true that evidence of prehistoric man-made tree houses have never been found by paleoanthropologists, but remains of wooden tree houses would not remain. Building tree platforms or nests as a shelter from dangers on the ground is a habit of all the great apes, and may have been inherited by humans.
