I hadn't considered concrete blocks... however, that is certainly a viable possibility. After doing a cusory look at this option, I saw that there are 'dry stack' blocks that really speed things up (you pour cement into the vertical passages).

I agree that some of the metal buildings are tacky looking but since we have 1.3 acres here, it wouldn't have to be directly next to the house.

pavulon and john70t, thanks for introducing the third option. I will have to check that avenue to see how it can work (plus, get the wife's buy in).
