My question is this, how far can you easily span your ceiling joists. I going to build a gargae/shop, built like a garage but it will be my shop, and most of the people that I have talked to want me to use truses instead stick built. I thought with a 10:12 pitch it would leave room upstairs for storage, office, or for any use. My idea is just 24x32. If 24' is to far with out a support wall is there is reasonable alternative. Cost is a factor, I do not want to double my cost just for a small room up stairs. Any ideas would be greatly appreciated. Thanks.
