Lots of variables. What part of the country the garage will be built at could make a difference. How high the side walls will be will also make a difference. Insulation and interior wall covering also matter, as might local building codes. The appearance of surrounding buildings may play into it as well, might not want to have the only garage in the area built like yours. Gene
I agree with those points. Also need to consider how large the building is going to be. Wood works just fine for a small structure, you'll need steel if it is going to be very large or if you want to support weight. I had to go steel on my shop since I wanted a bridge crane. No way are you going to hang a bridge crane from any normal wood structure. Wood is easier to work with for a backyard carpenter so if a person is going to finish it themselves then wood might be a good choice.
