I love keeping up with your progress on this building. The DH and I went through an effort (or several) like this when we first moved to TN--maybe I should show you what 8 - 10 years down the line will look like to you. Only mine isn't set up for a museum--mine is a dedicated sewing room with bed/bath for overnight (or longer) guests. It becomes "our" sleeping space when kids come with the visitors.....His space has his workshop and a hot tub, plus space for parking his vintage cars (and the son's recently acquired collector Harley).
