I want to build a loft above my two car spaces in the garage.
It is 20 feet wide. Length is flexible depending on wood suggested. 8, 10, 12, 16 feet etc. There will be walls on three side but I don't want it supported by the walls. I want it supported with it's own 2x4 framing to the floor? or 4x4 posts.
I'm trying to figure out how to span 20 feet in the garage without any posts in the middle. I'd hate to have a car knock it out some day.
