Did your dad build you a treehouse when you were a kid? Obviously, he didn't love you enough. If he did, he would have built you one that looked like this new tree hotel designed by Sweden's Tham & Videgard Hansson Arkitekter.
The "Harad's" tree hotel has a small kitchen, terrace, living area and sleeping area. There doesn't appear to be a bathroom or a ladder. That could make for a, um, rather uncomfortable night, at least for guests of the female variety.
The mirrored surfaces blends this conceptual design into the environment. I have a hard enough time remembering where my room is when they all look alike in a real hotel. What if all the trees look alike? Even worse — try finding your tree at night.
