The 'Roll It' Experimental House is probably one of the strangest and most interesting homes that I've ever seen.
Students Christian Zwick and Konstantin Jerabek from the University of Karlsruhe in Germany were the ones who designed the unique Roll It Experimental House. The whole concept behind this one-of-a-kind abode according to the two was to explore "mobile and space-efficient construction." The cylindrical home functions differently depending on the position that you roll it in. Turn it one degree and it functions as a workspace, turn it to another and it acts as a bedroom. There's even a space for a washroom -- just make sure the other person isn't looking.
The Roll It Experimental House is an interesting concept that truly defines the idea of compact living.
