A "domus" was a type of house commonly found in ancient Rome. It was typically a single-family residence designed for the wealthy, featuring a central courtyard called the atrium. The layout included various rooms for living, dining, and sleeping, often decorated with intricate mosaics and frescoes. The domus was an important aspect of Roman social life, serving as a space for family gatherings and entertaining guests. It often included a tablinum, which was a room used for receiving visitors, and a culina, or kitchen, where meals were prepared. The design reflected the status and wealth of its inhabitants.
