Chris and Niki Hampton were cramped but content in their tiny home, raising their small son and daughter. Then they were faced with a life-changing decision: Niki's sister had lost custody of her four children, who were facing foster care. The Hamptons opened their home to their nieces and nephews, aged two through eight, and began working toward full adoption. Despite their best efforts, however, their living situation had become increasingly unmanageable. Now "Extreme Makeover: Home Edition" has given this close-knit family a comfortable new home that can accommodate them as they grow, built with equipment from United Rentals.
