Though larger communal pit houses were sometimes abandoned, the new evidence shows smaller dwellings were continuously inhabited. For centuries, single families or groups of families would reside in the same house — building floor atop floor and expanding outward as needed.
Remains of the Campo Belo do Sul pit house revealed 12 preserved floors — five of them burned and collapsed.
The preserved architecture shows communities used evolving tools, techniques and ceramic materials to repair, renovate and expand their homes.
