Do you guys think using a clear poly roofing will be worth the extra cost? I am planing my wood storage suite and submitting my blueprint to the architectural review board for my sub division. It will be 23 ft long 5 ft deep and 6 ft tall in front sloping to 5ft in rear. The sides I will be hardieboard as to match my house and comply with the board. Front will be open and the rear will be lattice. I was going to use 3 x 5 pressure treated timbers for the base and the posts. I was going to dig the holes for the posts and fill them with concrete then use the metal anchor's used for decks. What Diameter hole and how deep? I was then going to use 2 x 4 16 oc North to south connected to the base 3 x 5 that are anchored to the posts What do you guys think ?
