At the Lexington project, Kevin finds the front gable wall of the second floor up and the roof framing underway. 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 the house, Tom shows Kevin the framing of the new farmer's porch. Inside, Kevin sees how the homeowners are getting by without a kitchen, which has been gutted. Later, Tom presents a solution to the ceiling height challenge in the old part of the kitchen. On ASK THIS OLD HOUSE, Tom replaces a broken window with a safer solution. Then, Kevin, Roger, Richard and Tom ask, "What is it?" Afterward, Richard shows a homeowner how to rotate a toilet.
