My two cents: I recently purchased a farm with a finished basement. My wife bought a loom that is set-up in the basement, and she said “you’re going to have to keep me company down here.” So my decision was easy. I have a large closet/shop where I keep my work bench. I was formally a jeweler. The bench is great for model work.
The best advantage I see in having a basement layout is the regulated temperature. It is cool in the summer-a great escape from the heat/humidity. It is warm in the winter- and no snow!
Have fun wherever you decide to build.
