Irwin decided the roof could not be salvaged, so he and two associates split 5,400 shingles from a single red oak tree and built the present roof. The cabin's floor was also missing, so Irwin located a contemporary puncheon floor at a smokehouse near Sneedville and moved it to the Arnwine Cabin. The stone part of the cabin's chimney was moved from the ruins of a contemporary house in the Laurel Grove community just north of the museum, and a stick-and-mud section was added. Over several years, the cabin was outfitted with authentic furniture, tools, and utensils from the region's pioneer period.
