Stumbling upon things like this is definitely the best thing. It sure looks like a door but it has some other functions as well. You can make shelves in the door and use it as a small library, turn it in to a plant holder or even attach sitting furniture to it. The idea definitely is innovative and functional for people who cannot afford the luxury of spacious places. Nevertheless, if you do the thinking, things, as books are sure to fall off the rack when you bang the door, leaving you with some extra work. So, this innovation definitely asks for some carefulness when it comes to application.
