Urban tree house

I've always loved tree houses. Don't know if its a guy thing or not, but that feeling of isolation, away from the whole world, away from it all. Or maybe its the fort thing, your own castle high on the mountain? Either way this would be very cool, I can imagine having this built behind one of the billboards over looking 71 southbound into the city. How cool would that be? A string of Aeroform condos built along Fort Washington Way. Or would Covington beat Cincinnati to the punch and begin building them along 75 south all the way up to the cut in the hill? Interesting.
