Post-frame buildings support a wide choice of interior and exterior finishes, roofing products, and architectural details. Almost any kind of interior wall finish can be used in a post-frame building. Vinyl, steel, and wood siding; stone, brick, and stucco; architectural foam, fiber cement, and backerboard are all viable options for exterior façades. Any roof pitch can be chosen, and covered with metal or asphalt, wood, tile, or slate shingles. It is typically more cost-effective to add overhangs, gables, dormers and other visual interest to post-frame than to steel-frame buildings. Other architectural features such as porticos, canopies, guttering, window and door trim, and wainscoting are also commonly added to post-frame buildings.
Post-frame construction accommodates high, open spaces and wide, clear spans. For religious facilities and commercial, institutional, and industrial buildings, clear-spans in excess of 100 feet and large uninterrupted spaces allow for open, flexible floor plans uninterrupted by load-bearing walls or columns.
Financial institutions with limestone entryways, traditional concrete-block schools, brick-and-mortar office complexes, strip malls and other retail establishments, warehouses and other industrial facilities-- all can be most quickly and economically erected as post-frame buildings.
