With a growing family and a need for more space, a young couple call on contractor Jay Baker to help get the job done. There's not much time for a transformation because a baby is on the way and mom is coming to stay. Jay's solution is to turn a worn-out, old bonus room into an eye-popping living room, bedroom, kitchen, bathroom and laundry room. It takes a small army of men and the power of a 320-gallon propane tank to help this bonus room break out.
