I recently had my 30x60 finished up...it's a pole barn and I was wondering metal vs pole barn when I was shopping around, but I used a 30x60 nextdoor that is metal frame and my shop feels WAY bigger. I'll frame in the ceiling for storage above the rafters, which you can't do with metal frame. I can't wait to start building up the inside and get my electrical done...We broke it in last night with a crab boil/bonfire.
