As part of our 25th anniversary season, Kevin returns to the show's first timber frame barn project, the Concord Barn, to see how the building has held up over the last 15 years, and learn from homeowners Lynn and Barbara Wickwire what it's really like to live in a barn. Chimney specialist Mark Schaub oversees the prep and pour of a new flue for the living hall fireplace. Back in Carlisle, Richard shows Kevin the anatomy of the new submersible pump that will be 400 feet underground inside our new well. Norm and Tom shows Kevin how to work with the latest generation of pressure treated lumber while building the front entry porch.
