I'm in the early stages of planning a pole barn build for next summer. I have a couple of questions. When ordering 6X6 posts, do I need to order extra to frame out for the doors or is there another way? Would it be ok to build in stages or am I better off waiting to have enough money for all the material before starting to build. I was thinking 3 stages. First stage is doing all the frasming, second the roof and third siding. There may be a few months between phases. It that Ok? Thanks! TC
