Sometimes it's what's behind the walls that makes all the difference. When John and Anthony take a look at Joel and Maria's kitchen, the first thing that stands out is an unusually thick wall. After a little exploratory demolition they discover an incredible hidden fireplace which completely changes their original design. But as construction progresses, the fireplace they fell in love with becomes their biggest nightmare. Will this hearth be the centerpiece of the home, or will the whole job go down in flames?
