Do you always make basements in your houses?

I most often put basements in my builds, but not always. The area I grew up in has homes that have basements so it is what I am familiar with. I use them mainly for storage, putting holiday decorations and shelves for storage. I also use them for storage of canned goods, now that we have canning in the game. A basement is great for expanding your home as well, and I will add a family room, laundry room, or others if I need to. And of course, the basement is perfect spot for my spellcasters to have a cauldron and items needed for making potions!
