Which Roman classical building type was primarily for the wealthy?

The domus was the primary type of building in ancient Rome designed specifically for the wealthy class. It was a single-family house that featured an atrium, a central courtyard, and various rooms designed for different functions, showcasing both luxurious living and social status. The architecture reflected the wealth and taste of its owners, with elaborate decoration, spacious layouts, and the inclusion of private gardens, often situated in urban areas.

In contrast, the curia served as the meeting place for the Senate, while the basilica was used for public gatherings and commerce. These structures catered to broader community functions rather than individual living spaces. Insulae were multi-story apartment buildings designed to accommodate the lower-middle and working-class citizens, providing more affordable housing options. Thus, the domus distinctly represents the luxurious and individualistic living to which wealthy Romans aspired.
