A pole barn under construction. A pole barn under construction. Pole framing or post-frame construction (pole building framing, pole building, pole barn) is a simplified building technique adapted from the labor-intensive traditional timber framing technique. It uses large poles or posts buried in the ground or on a foundation to provide the vertical structural support and girts to provide horizontal support.
Pole Barn Basics. Building a pole barn requires planning. The first consideration, of course, is how big it needs to be. Pole barns are typically built in increments of 10 or 12 feet, such as a 20-by-36 feet. Poles are typically set in the ground like fence posts, so itâs important to use treated lumber, and most of the barnâs strength comes from the sheet metal siding and roof.
