Post-Frame is very flexible in terms of both appearance and application. 

Post-frame buildings may be designed to match almost any building look, and to meet the needs of almost any purpose imaginable for a low-rise structure. 

Post-frame buildings are typically designed to accomodate one or two stories.  Two-story post-frame buildings with a useable attic loft are increasingly common.

Post-frame can accomodate clear-spans in excess of 100 feet, so you may design a building with lots of interior flexibility without being tied to installation of load-bearing walls or columns that may break up the floorplan within a building's footprint.  You may place walls wherever you like and change them later - or have none at all if you need a large open floor.  Also, pretty much every type onf interior wall finish may be accomdated using post-frame, and because the structure is made of wood one can avoide using "nailers" and other means that may be necessary for interior walls in some other types of buildings.

Post-frame buildings may sport almost any type of exterior facade.  A wide array of beautiful metal siding, wanscoting and roofing products are often used on post-frame buildings. Brick, cultured stone, limestone and other new siding products may be installed in any season for less cost and in less time than conventional brick and stone walls.  Architectural foam, fiber cement siding and backerboard, stucco, vinyl siding, wood siding and most other types of siding are all viable options for finishing a post frame building. Architecturally, any structure you see driving down the road could be a post frame building, because the one may match almost any exterior building finish.

Churches, schools, museums, annexes and other public buildings are frequently erected using post-frame methods. Industrial facilities such as production facilities, airport hangars, machinery shops, warehouses  and other industrial fabrication and storage facilities are commonly built with post-frame techniques. Commercial buildings, such as office complexes, strip malls, restaurants, motels, convenience stores, home and garden centers, general stores and other retail establishments are all well-suited for the efficiency offered by post-frame. Homeowners may consider post-frame for residential accessory buildings such as garages, workshops, storage buildings, or even for a new home.

Post-frame offers the most flexible approach available to meeting almost any low-rise building need.
