Mark and the guys wade in water to save a dilapidated springhouse, then they rebuild it back at the bone yard.

Working with a passionate client, the crew builds a huge double-pen log cabin on a platform 13 feet off the ground.

The Barnwood Builders go deep in the holler to reclaim a rare one-room log schoolhouse full of history. Back on the boneyard, the schoolhouse gets a whole new life.

The guys visit South Carolina to tackle the 100% cabin and renovate it into a hunting cabin.

The team brings an Appalachian-style cabin all the way to western Colorado. At the Canyon of the Ancients Ranch, they explore the stacked stone ruins of the ancestral Puebloans and also leave behind a legacy of their own. Before they leave, they also rebuild the Virginia spring house which will support a living roof.

Mark and the guys use over 100 antique logs from two tobacco barns to build a dramatic entrance for their client's property. The drive-through double corn crib requires a whole lot of teamwork, and involves some of the trickiest notching they've ever done.

In the shadow of the New River Gorge Bridge, the Barnwood Builders work with three centuries of materials and techniques in one project. Using custom 21st century steel brackets and hand-hewn 19th century beams, they create a one-of-a-kind pavilion for the Wild Rock Community Center.

The guys take down a massive double-pen barn in southern Indiana. While they work to save every log and barn board, Mark visits an incredible lodge built from a different barn they took down in nearby St. Meinrad.
