Nathaniel Graf moved into his tiny, eco-friendly house in Swarthmore, Pennsylvania initially as an experiment -- but he loved it so much, he decided to stay.
Graf, who works in the office of sustainability at Swarthmore College, says living a tiny house comes with a bunch of opportunities to reduce his carbon footprint and help protect the environment. The A-frame ceilings and spacious layout also gives Graf a sense of space despite the home being tiny in size.
Despite the home's size, Graf says he couldn't see himself living anywhere else.
