I'm in the process, have been, of designing my shop etc to build this winter. I'm back and forth on a few things but the layout will get straightened out. Here's the questions...........steel or wood? Both have about the same outside walls and roof (tin). I'm just a little hung up on a steel or wood building. From what I've seen, wood is less expensive. I can design the building and have a lumber place or saw mill cut everything for me and order trusses. Steel or wood and an educational "why" please. Thanks.
