Tommy creates an arched feature for the new gable above the front porch stairs that mimics the arch in the side gable of the house. Then he adds the finishing touch to the front porch: cedar columns. Kevin travels to Vermont to see an artisan create a custom floorcloth for the kitchen. Tommy builds the porch railings, which require a special detail in order to meet code. Kevin begins a labor of love: a tree house for the kids.
