This hotel in Sweden is made of light-weight aluminum which hangs around the base of a tree. The exterior reflects the surroundings and the sky, which creates a camouflaged refuge while the interior is all made of plywood and windows that give off a 360 degree view . The mirrorcube can accommodate two people and includes: a large bed, a small kitchenette and bath, a living room and roof terrace. But perhaps the most brilliant part is that to prevent birds from flying into the cube an infrared film, visible only to birds, is laminated into the glass panes. The cost for one person per night is just over 400 dollars.
