Madison and Mark Talley of Tall Architects moved from a camper into their self-designed, self-built space in 2017. The couple and their three-year-old son, George, have happily made the tiny house a home in Vancleave, Mississippi. Madison points out that the pod concept would make it easy to add an extension if necessary. "We see it as a house that can grow with us—and that we can pay for as we go along."
