In many Indigenous communities of the South American tropical forests, the maloca—a large communal dwelling—serves as a physical manifestation of the group's social organization. These structures can house hundreds of individuals, sometimes encompassing an entire tribe.1

The internal layout of a maloca reflects specific social distinctions, as the space is customarily divided to assign a designated area to each family and, in some cases, to individual members. By providing a structured environment where every person has a defined place, the architecture reinforces the social order and the collective nature of the community.1

While these dwellings lack interior walls, the spatial arrangement serves as a functional map of the group's social structure, mirroring the way other Indigenous villages use circular layouts around a central plaza to represent segments of their society, such as clans or extended families. Through this organization, the maloca integrates the economic and social life of the people into a single, cohesive living space.1
