The domus is a classic urban construction of the Roman housing repertoire, which also included the insulae, private houses intended for the people, built on several levels, used in ancient Rome.
The domus was a private urban house consisting of several rooms, connected by a portico, with a peristyle or atrium in the middle.
The domus was different from the villa, which was a private residence, possibly even luxurious depending on the rank of the owner, located outside the city walls.
The villa rustica, on the other hand, was situated in the countryside and had special rooms for managing the fields or, in the most important cases, the latifundium.
