Could you please share if there are 2 or 3 columns on each side of the entry porch (behind the trash can). Can't tell if there is a third column, hidden. What size are the columns? Really like this look and have a 20' wide porch with a current column design that hides areas flanking the door that I don't want hidden. If something like this works load-wise, I want to do it. Will speak to our builder and architect, but would appreciate knowing size of columns and if there are 2 or 3 on each side. Thanks in advance.
