About fifteen years ago, I wanted a deck for my seasonal. So I built five 4 foot by 8 foot sections creating an 8 x 20 foot deck. Set them up by using regular concrete blocks. Tied them together using 1x4 boards across the front face. Then we got a park model and needed a walkway to the back door. Two of the sections became the walk way with railing, the other three became a patio on the ground in front. Then we bought 20 acres and built a house. The three that were the patio came along with us and now two of them are the front stoop and one of them is a spare in the garage. The condition of the wood is as good today as when I built them. I can't believe they are fifteen years old. The moral of the story is, make what you build today portable and versatile and over the years, you will get your moneys worth.
Can't catch 'em if you don't wet 'em.
