ABSTRACT:This article explores the relationship between dwelling space and the lifestyles and social identities of the Roman bourgeoisie during a period of great social and cultural change. Concentrating on a few exemplary situations, the neighbourhoods and homes of the bourgeoisie are examined through the analysis of elements such as forms of behaviour, social relations, dress codes, building typologies and domestic interior furnishings. What emerges is the importance of dwelling space to the development and expression of bourgeois social identities, as well as the plurality of the latter and their evolution over the period examined.
