Fantasy Bunk Bed

I'm designing a room for a client right now who ideally wants a full bed under a twin bunk.  I completely understand the functionality of a piece like this but I usually don't like the way they look because they generally feel lopsided. I did though come across the Fantasy Bed while looking for alternatives and I think it is stellar!

If you have a wall that is at least 105" long, it is a great compromise and solution. Granted it comes with a hefty $6000 price tag.  If you have a good carpenter he can probably build you a custom one for right around that.
