This is taken from a radio show called Science Friday. This is about a couple who were inspired to design and build their own tiny house with mobility because they were tired of paying 1200 monthly in apartment rent. :)
From SciFri on Youtube:
Chris Tack made seven trips to Goodwill to get rid of his stuff, before moving into the 140-square-foot home he and his wife Malissa Tack designed and built. Constructed on a trailer bed and parked in Snohomish, Washington, the house is more than enough space for them, the couple says. And one advantage of a home on wheels, the 29-year-olds say, is that you can always move.
