Barn wood wall
We live in a "barndominium". We converted half of a barn into our 3500 sq ft home and the other half into our workshop. The walls in the workshop were just insulation and needed a rustic makeover to match the interior of our home. I covered the entire wall with OSB, painted it black, then cut the barn wood and attached it. It was a little frightening working at the peak that is over 24 feet high, but I think it turned out great!
