Romano-British houses took inspiration from the Mediterranean world. These foreign ideas may have been transformed in the process of transmission, but they remained a powerful influence in all aspects of RomanoBritish design. Baths, wall paintings, tile roofs, mosaics, colonnades and a host of other architectural features arrived in Britain in the wake of the Roman conquest. The purpose of this chapter is to set the British evidence in this wider context. By exploring the origins of classical house types, we can describe those features of elite architecture that emerged from the Hellenistic east to influence Roman provincial fashion. The aim is to show that Roman architecture was not just of Rome, but part of a broader Romano-Hellenistic culture that shared certain common approaches and concepts.
