Different parts of our nation seem to favor particular styles of fabrication methods. Where I'm located pole barn style is favored mostly by those wanting to simply park their equipment, as in: tractors, trailers, tillers and other farm equipment. But if a workshop/garage is wanted for woodworking, metal working or other such uses, a stick built is preferred.
Based on the frequent questions read on GJ, I often see those with pole barns needing ways to insulate, hang cabinets/shelves or pour the concrete floor, which are usually non-issues for a stick built structure. Personally, I prefer a good solid reinforced concrete slab and footings over a structure supported on wooden posts/poles. For me, my shop is my home, and I much appreciate the benefits of a stick built structure.
