Overhangs are a good subject. That is one place where steel makes it easy. The steel building company that I worked with just asked me if I wanted overhangs and how big I wanted them. I had a medium overhang in the front so I can unload a truck without getting wet in the rain. At the rear of the building I went with the max allowed overhang to provide a carport/RV parking area. I also asked them to finish the underside of the overhangs with a contrasting color just to make it look nice. They mounted lights on the rear overhang area so I can see what I'm doing in the dark.
