This study is intended to be an attempt to identify the social structures associated with the dwelling in the Chalcolithic settlement from Hăbășești, Romania. Starting from the analysis of dwellings, the intention is to identify the major components of the household: social, material and behavioural, and the determination of the nature of the activities carried out within the structures. Taken into account are the size of the dwelling, the number of rooms, the presence of combustion structures and the inventory of dwellings.
