The research into changes in the Sentani indigenous people's settlement spaces can be assumed in cultural and environmental relations. The most priorities highly depend on cultural and environmental backgrounds since they are the main factor determining the course of the evaluation of changes in the form of the traditional settlement hierarchy built. The significant aspect of the innate form of the traditional settlement hierarchy is the changes in the traditional community-built environment into opportunities affecting the changes in traditional settlement patterns. The interdependence between forms of housing and settlement patterns, including houses and settlements, is inseparable from one another. Community occupancy is an essential component of the establishment of settlements they have. In addition, none of the dwellings can be seen as independent buildings standing alone in the natural landscape. Configuration of indoors (dwelling community) and outdoors (settlements) makes an interaction formed entirely by the mutual dependence between the two. In this paper, this method used compares a series of traditional settlements ranging from the most original to the most changed in 1903 and 2022 in the remote areas closer to the original condition. Field studies were conducted in traditional settlements of Sentani indigenous people. Observation, sketching, photography, fieldwork notes, and in-depth interviews were used as research techniques to explore rich data and phenomena within the socio-cultural and environmental contexts. The relationship between the forms and patterns of traditional settlements is determined by the layout correlation between the mass of the building and the patterns of settlement arrangement. This is the focus of this research based on the relationship of cultural changes in the hierarchy of traditional residential spaces.
