I know a guy who has done what you are talking about. Built a 16 ft tall pole building, put a apartment in the upper 1/4 with workshop/man cave under it, regular garage type pole building in the rest. It works but it will never be a mansion. Think about it as a In-laws possible rental after you build a real house..
Also there is the couple on TV who have a metal sided house that is half pole building. Lee and tiffany the Crush Deer hunters
