Post frame construction is a highly efficient building method that involves the use of large posts or poles secured in the ground or mounted on a foundation to provide the structural framework of a building. This method is distinguished by its reliance on posts to bear the load of the roof and floors, eliminating the need for interior supporting walls.

The framework created allows for wide-open spaces, making it an ideal choice for a variety of building types. Post frame buildings are known for their quick construction times, cost efficiency, and flexibility in design. The technique has evolved over the years to incorporate modern materials and methods, enhancing durability and energy efficiency.

The construction process begins with setting the posts into the ground or onto foundation brackets, which are then connected with horizontal girts to form the walls. Trusses are mounted on top of the posts to support the roof. This structure can be clad with a variety of materials, including metal siding and roofing, wood, or even brick and stone veneers.

Insulation can be easily added to walls and roofs, making post frame buildings suitable for climates that experience extreme temperatures. Due to their structural integrity and versatility, post frame constructions are used for commercial, agricultural, residential, and recreational buildings.
