At the Lexington project, Kevin finds the front gable wall of the second floor up, and the roof framing underway. Around back, Tom installs a 24-foot long LVL to temporarily hold up the second floor while he adds new structure. Then, they frame the rest of the addition roof. Nearby in Lexington's historic district, architect Frank Shirley shows Norm how people have been using front porches to lend character and charm to Colonial style homes for hundreds of years. Back at our house, Tom shows Kevin the framing of our new farmer's porch and then they build a small overhang to extend the look across the garage. Inside, Kevin sees how the homeowners are getting by without a kitchen, which has been gutted and is ready to be expanded thanks to a 24-foot steel beam that will carry the weight of the second floor. Later, Tom presents a solution to the ceiling height challenge in the old part of the kitchen: a structural ceiling that will allow him to gain some height over the islands, while allowing for both adequate structure, and a clever chase for wiring.
