The guys transform a timber frame barn into a modern home for an architect in Louisiana. As they build, they explore the rich architectural history of the Bayou State. Afterwards, they visit a cabin Mark repaired years ago and an historic French-Creole house nearby.

Mark Bowe and his crew work to salvage a cabin that saved their business. It takes a variety of repairs to bring it back to life, but once it's up, Katherine has the best surprise of all. Later, Mark's pal Eddie makes a lamp out of reclaimed materials.
