Host Matt Blashaw challenges Tim and Michelle Gauna to convert their unused garage into an attached dining room. They'll have to complete the project like the pros for a chance to win cash. Matt and a contractor expert will inspect the new dining room and estimate it's cost. If their estimate is more than what was actually spent, Tim and Michelle win the difference. Tim must break through walls, raise the floor, and perform the electrical work while Michelle endures the headaches of insulation and Tim's reluctance to read directions. Plus, this couple has four kids ? including two young babies ? which means dedicating time to the renovation is next to impossible. With major surprises and challenges, the whole family will have to work together to pull this off. They must manage the fine details of this addition to outwit the pros, or their shortcuts may end up costing them in the end.
