Tricky one the use of Wood outside. I have had a Wooden Platform outside since the late 80's. Only just completely given up the ghost,mthough to be fair the Subbase that the Sleepers were nailed to had been replaced once in the 2000's. But the Sleepers survived and still a few were okish when I finally binned it last week. Outside for things that are to stay in place I would always recommend something Plastic or such like. Roofing Soffits are a great resource and if you can have a good overhanging roof you can cover the sides with Cofee Stirers or Lolley Stocks as I did with Andy Rush's Carolstadt Swiss style building. Built around 2008 and still going strong. Though always good to have a Gap between the wood and ground perhaps scribed to represent Brickwork.
