Pole barn construction (also referred to as post-frame construction) is an engineered wood-frame building system that - in simple terms - involves using posts buried in the ground to support the weight of the walls and the roof. The walls in a pole barn are not load-bearing because the poles support the weight of the building, reducing your framing costs. Pole barns can look like a conventional home just as easily as looking like a garage or - you guessed it - a barn.
