After nine weeks and 19 renovations, the final two designers meet their final challenge. In their biggest renovation to date, they must transform two dream beach homes in Ventura, Calif. Luckily, they won't have to go at it alone. They are reunited with a few surprise guests to help them. One designer will win the grand prize of $250,000 and be crowned as the first American Dream Builder. Nate Berkus hosts while Eddie George and Monica Pedersen serve as judges.
