He used No. 2-grade pine boards for the walls' horizontal planking, which cost him less than drywall. "It typically has more knots, but once they're sealed and painted, you'll never know the difference," says Allen.
Soybeans and pine are both readily available in Arkansas, so Allen used soybean insulation and pine timber to cut back on material-transport costs and support local industries.
