I found this really intriguing

Christian Schallert, a photographer based in Barcelona, demonstrates the utility and simplicity of an apartment that is 258 square feet--a third of my own. He has recently moved out, now that he is in a relationship, for it really is a one-person bachelor pad. But it's really interesting what can be done in such a small space.
