Billy and Megan Libby are teachers in Asheville, North Carolina, who live in an 1,100-square-foot condo with their son, Nate. The couple is about to get a big surprise—but they think they're only asking Nate a decorating question via satellite. "Basically, we have one big living space and we have to have a dining area and a living area and a computer work space, and we just want to know how to define the boundaries in this one space," Megan says.
