Functioning for Four

Mason and Shannon moved into their 2,000-square-foot home in a neighborhood perfect to raise their young son, Luke. After adopting their teenage daughter, Carmen, they felt as though their house may be a little too small for a family of four. Mason wants to find a larger home with enough space, privacy and function for all family members, but Shannon wants Carmen to have stability and stay put. Will realtor David find them a family ready home? Or will designer Hilary make daily life immeasurably easier by reinventing many of the home's hotly debated spaces?
