Re: (update question)Steel Garage vs Wood
Which ever way you go...make sure there are no support structures (lally columns, etc.). My first garage had a lally column in the middle, and no matter what it always got in the way. I got smart the second time around and used a steel I-beam down the center, spanning 30 feet.<br /><br />Re the wood vs. steel...you don't mention if is attached to another structure or needs to architecturally conform to any standard, etc. Much will depend on your climate and foundation requirements. Wood may require a heftier foundation with full footings to distribute weight. Steel has fewer bearing points and may allow a monolithic slab with fortified points on bearing center...for example.
