Beautiful design, but that's it. No person in his or her right mind would use stairs like that on a daily basis in their home. Yes, it looks more dangerous than it is, with the "hidden handrail wall", but it's still fucking dangerous. Ever slipped on "normal" stairs? Imagine what happens on this thing, halfway down. That's potentially lethal. Not to speak of kids, elderly or disabled people. Accidents are bound to happen with this thing.
