I envy you guys with basements. They may seem common place to you, but they are rare in Texas! I have long said if I ever build another house, it is going to be underground.
Often think of building a wine making room/cellar/food storage area. I have three areas around the place where I could, but all have their drawbacks....upstairs, a bit small, or hard to get water into.
Always keep coming back to dig a hole and do a cellar. Easier said than done when you live on top of a limestone hill! Even checked into a "climate controlled self storage unit"...they said they maintain a constant 70 degrees, but my IR thermometer showed 82 and it wasn't even 95 outside that day.
