They glued it directly to the concrete? Is the floor a hard wood or a manufactured product?

I ask because it was my understanding that real wood floors require a sub-floor over concrete. That makes the whole thing about 1.5" deep. To do this, I would have to step up onto the wood from my adjacent tile and would throw off the step height out of my front room. Otherwise, I'd be all over a wood floor in my front room.

Looks great, by the way.
