This study examines settlement evidence from south-eastern Norway during the Late Neolithic and Bronze Age, revealing unique aspects of regional architectural and social organization. Notably, smaller and uniform house sizes suggest a divergence from the monumental power displays seen in southernmost Scandinavia. The uniformity in house sizes and significant spatial distances between contemporary houses imply a social structure akin to segmentary societies with symmetrical power relations, reliant on mobility and mixed subsistence practices. Changes in settlement patterns and house sizes during the Late Bronze Age could have been the result of increased social stratification or responses to population growth. Overall, the settlement patterns and house sizes in south-eastern Norway reflect a society that, while connected to the broader Nordic Bronze Age world, developed distinct social and economic strategies. These findings highlight the importance of considering regional variations and responses to environmental and social challenges in prehistoric societies.
