The main factor that has driven the rise of common interest housing is that it facilitates increasing population density, which is profitable and efficient for developers and cities. Residents often become unhappy with these high-density shared ownership arrangements, but here's evidence that these patterns have persisted from ancient to modern times.
"Researchers from the Santa Fe Institute and the University of Colorado Boulder have revealed that a common pattern of development and similar characteristics can be observed in ancient as well as modern cities. Large populations and dense areas are the features of modern cities, which were also exhibited by ancient cities. As per the new study, the inhabitants of ancient cities having bigger and denser settlements were more efficient. The study has been detailed in the journal PLOS ONE."
