Double decker design

In many small places like residence rooms, the beds are elevated, such that a stack of drawers can fit under them. This is a great efficient use of space, and also achieves the "coolness" factor of being on a top bunk. And often you can crawl under the bed, behind the drawers, in your own secret fort area.

In many new places these days, the TV is placed above a fireplace. I find this terrible, having the TV so high. And if the fireplace sticks out and you have a flat panel TV, viewing it from a couch, the bottom of the picture might be obstructed. That's what gave me the idea of having an elevated couch, in a similar manner as the elevated beds! You could get a bunch more useful storage space under there, and you'd still have a great view of the TV. You wouldn't have to worry about the dog being on the couch either. In an elevated single chair, it would feel like a throne, looking down upon your subjects. A final advantage is if you have a bunch of people over to watch a movie or hockey game, instead of crowding around at oblique angles, you could have another set of chairs set up like theatre seating. As long as the upper people have clean feet. I think it's an awesome idea, and perhaps one day I will get to implement it.

Unfortunately other than the bed and living room sitting spaces, I'm not envisioning the double decker design having much applicability in other parts of the house. Any ideas? Double decker garage would be cool, but not as cool as having a rotating parking pad. And with the top deck, it would be more fun to pretend it's a barn and have hay up there and... sounds itchy.
