Insulae, Ostia Antica

In Roman architecture, an insula (Latin for "island," plural insulae) was a kind of apartment building that housed most of the urban citizen population of ancient Rome, says Wikipedia, including ordinary people of lower- or middle-class status (the plebs) and all but the wealthiest from the upper-middle class (the equites).

The traditional elite and the very wealthy lived in domus, large single-family residences, but the two kinds of housing were intermingled in the city and not segregated into separate neighborhoods.[1]

The ground-level floor of the insulae was used for tabernae, shops and businesses, with the living space upstairs. Like modern apartment buildings, an insula might have a name, usually referring to the owner of the building.[2]
