Very nice looking barn. As a design engineer, the construction looks extremely sturdy.
This ole house we bought in the country came with a 2-car carport. It has a slab, but is about 6" below grade. Weird...I know. Sux not having a shop that I've been accustomed to over the years, but have already researched polebarn construction for a 24' x 36' garage/shop. The costs were extremely reasonable when compared to typical stick framing.
Thanks for sharing your construction project. Enjoyed every pic & narrative.
