Dream Big, Live Small: A 350-square-foot NYC oasis that transforms in seconds

Graham Hill lived large -- a fancy house and fast cars -- but this entrepreneur traded it all in for a tiny apartment in downtown New York City.

While Graham has only lived in his apartment for a little over eight months, he couldn't imagine living anywhere else. As the founder of TreeHugger, a media outlet dedicated to driving sustainability mainstream, Graham has always looked at things in an environmental manner. Not only is the businessman's house extremely functional, but it also leaves as little of a carbon footprint as possible.

From retractable walls to multipurpose couches, this 350-square-foot apartment is a tiny home lover's dream.
