Wow, great project, I'm jealous.

If you're thinking of storing anything heavy upstairs, maybe cut a hole in the floor so you can lift things up through the hole by a hoist attached to the roof joists. The hole can be covered by wood when not used. Or, do an old fashioned barn-hoist type beam sticking out of one end with an opening to move the item in. If you aren't storing engines or other big bulky/heavy items up there, never mind! Good luck with the build.
