I want to build a pergola on top of my deck. Instead of using 6x6 posts I'd like to build square columns out of 1x6 treated lumber. I basically want to build a box to support the structure. I believe that this box column will support the weight of the structure, as I have seen these types of columns used to support porches on older homes. Any thoughts on this? TIA JD
