Look: DIY Wine Storage Under the Stairs!

It seems that both stairs and wine racks have been extremely popular recently here on AT, so when we found this hidden gem in a friend's basement, we just knew we had to share... Our friends revamped an existing storage cubby under their basement stairs to house their wine collection. We love the built-in look and the creative use of a previously under-utilized space. We have used the space under the stairs as a make-shift coat closet before; what creative uses have you found for that space?
