All of the lumber is pressure treated, the lumber yard had it bundled out in the yard. I have it tarped and set along the side of the house in the shade.
I'm going to use deck screws to assemble everything, I don't have a nail gun and honestly prefer the holding power of screws. I don't claim to be a professional carpenter but learned a lot from my Dad and Grandpa, both were great at building anything. I did all the drawings for the permits, just hope it looks as good when it's done.
