Split Level Bedroom

I love the idea of a split level room, it adds a whole new dimension and creates a great focal point, as well as making best use of the vertical space. I'm going to look into some human ergonomics books to try and get an idea of whether a split level design is plausible for the room i'm redesigning for my university project.
