This chapter examines private architecture in Late Antiquity, focusing on the evolution of domestic structures and their role in social, political and religious life. It explores various building types, including domus, villas, insulae, palatia, praetoria and episcopia. The chapter argues that private architecture during this period was highly diverse, reflecting both continuity and transformation. While wealthy residences – whether aristocratic homes, episcopal residences or governor’s palaces – shared similar monumental features such as triclinia, courtyards, baths, and reception halls, often blurring the distinction between private and official spaces, imperial palaces frequently evolved from earlier residential buildings. At the same time, Christian bishops adapted aristocratic architectural models for their own use. Overall, archaeological evidence suggests that private architecture played a crucial role in expressing social status and power, with the design and decoration of homes reinforcing elite identity. At the same time, this study highlights how the economic and political shifts of Late Antiquity shaped domestic architecture, leading to both the persistence of elite housing and the gradual decline of multi-family insulae.
