Instead of saying what's in it, I'm going to show what it is. That's the stainless storage unit that Costco sells for about $100 if I remember correctly. The space it's in was dead space under stairs that go to the second floor. After the addition/remodel got to about 4x our original budget (ha!) we decided to temporarily not put doors there and I got a couple of cheap, washable curtain panels from WalMart. Five years later I'm glad I did. I have full access to every inch. Like someone mentioned above, I have NO food in my kitchen cabinets which is a very big deal for me. Anyone who has some extra space might want to consider this. I think they also have one about half that height.
ETA: I also have some extra shelves in the laundry room and I'm considering changing the door to the upstairs to swing in the opposite direction so I can some shelves on the other side. Where there's a will there's a way.
