Kind of depressing how some people two millennia ago had bigger homes than most people alive today. Then again, if they were alive today their homes would be 10x the size.
In modern societies such super rich people flock to major cities, but in pre-industrial societies relocating would leave familial assets under-attended. Accordingly a well adjusted wealthy person would arrange for an excellent standard of living adjacently to their possessions
Also Roman economics were not really very local. The Romans had a large road network and were very mobile and traded even farther. You have for example Pelagius, a figure in church history, who was born in Britain and died in Egypt.
Even if you compare homes of ultrawealthy then and now I expect that most would take homes of XXI century.
