Creosote treated lumber works well for structures like bridges & pole barns, & is good for fence posts & telephone poles, but not so good for houses or decks because it stinks & bleeds stickey gunk. I'm sure that various forms of water-resistant or water-proof building products will become available in the near future. One product that I have seen is a mixture of wood chips & plastic that is supposed to be impervious to moisture & stronger than wood. These composite materials will eventually replace treated wood products.
