I would consider the sealant and deck stain you choose carefully but it looks like there's a great deal of structural damage here. Drainage could definitely have had an impact. You maybe want to think of an entirely new design that isn't so demanding from an upkeep standpoint.

Re: what did you do in your garage today?
Today I categorize the items in garage and evaluate things like luggage and paint and store them in storage room.
Those pictures are awesome, this seems like a really cool creative undertaking. Have you decided whether or not you plan to use wallpaper for the interior? I'm sure you could find a really nice design that goes with the colors in these pictures. Best of luck, can't wait to see how it comes out!
