Post frame construction, often called a pole barn, has become one of the most popular building methods for property owners across rural, residential, and agricultural land. From shops and garages to homes and barns, post frame buildings offer flexibility, strength, and cost control that traditional construction often cannot match.

Choosing the right size and design for a pole barn is one of the most important decisions you will make before building. Whether you are planning a pole barn garage, a workshop, or even a barn house, the layout and structure should match how you plan to use the building today and in the future.

One of the most common questions people ask when researching a pole barn is simple: How much does it cost per square foot? At first glance, that sounds reasonable. Square foot pricing is familiar, quick, and easy to compare. The problem is that for pole barns, square foot pricing often creates more confusion than clarity.

Eave height, often referred to as eave wall height, is the vertical distance measured along the wall column from the finished slab or finished grade up to the bottom of the roof truss at the eave wall. In post frame and pole barn construction, this measurement defines the true usable wall height inside the building.
