I was thinking the same thing... I need to take advantage of the vertical space. I figure the first 15 feet will be left open on either side, then tools, work bench etc. then the back ~15' will be storage of motorcycles atv's etc. But I'd like to build a loft, for even more storage above the motorcycles and ATVs since they're only about 5' tall, and the ceiling is about 15' I need to do something there.
