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.
Accordingly, a pole barn with the posts set 12' center to center would use a 12' wide door, covering each post 3 and leaving an 11'6 inside opening. With an overall rough opening height of 10' floor to header, we would make our doors 1 less in height to clear the pebbles.
