Life up in a Korowai tree house - West Papua, Indonesia :

The korowai, also called the Kolufo, are a people of southeastern Papua (i.e., the southeastern part of the western part of New Guinea. They number about 3,000. Until 1970, they were unaware of the existence of any people besides themselves. The majority of the Korowai clans live in tree houses on their isolated territory.

 The distinctive high stilt architecture of the Korowai houses, well above flood-water levels, is a form of defensive fortification- to disrupt rival clans from capturing people (especially women and children) for slavery or cannibalism. The height and girth of the common ironwood stilts also serves to protect the house from arson attacks in which huts are set alight and the inhabitants smoked out.
