Would want in a custom closet. Would want the shelves angled a bit so I could see the shoes easily and a dowel added to hold them in place. Also like the cubbies for flip flops and flats. Would also want a hook added for a ladder so I could reach the top.
If I ever won a big fat lottery I'd have hidden passages all over my house, and one would be like a Chinese puzzle where I had to move certain parts of a few adjoining rooms to get into the hidden one!
