There's simple, small living. And then there's this. The four homes featured here are not just small. They're tiny. Each clocks in at less than 40 square meters (430 square feet) and yet manages to feel cozy and not even cramped. Of course, the reality of tiny house living might be a little different -- after all, there are no actual human beings in this lovely, organized photos. But whether or not you want to live the simple, tiny life for yourself, you can't deny the urge to simplify that grabs onto us all when we see images like these ones.
