@Eric
Good question.
As you can see by the photos… I built the wall tight to the vinyl siding of the house.
Since that shed wall can’t get any rain or exposure… I didn’t put anything on the plywood.
The shed’s vinyl corners also help hide the backwall. Even if your standing there and try to see the shed back wall… you can’t, because of the vinyl corners. There is probably a 1 to 2 inch gap between the house wall and shed wall.

Thank for the information and including a google sketchup model. A question though. How did you cover the wall closest to the house?

Thanks again.

I used my air staple gun to fix the position of the aluminum … then the NPC Solar Seal industrial caulk.

Your project sure shows well. Wondering about how your flashing is secured between the deck. Did you nail it in place or is it held by caulking only?

Wow! That looks great! We’re thinking of doing the same sort of thing. Wondering if you installed a gutter (or any other way of diverting the water run off from the trough)?

I suppose a wood floor should work. I just wanted a concrete floor. In either case (if your further north like me) then you need to allow for frozen ground heave. Sure would love to see photos when your done.

I am also about to build a deck and office below. I was wondering if you thought about using a wooden platform floor or if laying concrete first is the way to go. I thought wood flooring would be less expensive. Thanks.

It is impossible to do the flashing with the top deck boards in place.
I used screws to put down my top deck boards, just in case I need to remove the boards.
MAKE SURE YOU USE SOLAR SEAL BRAND caulk for sealing the flashing to the joists. That stuff is the best! Ask anyone who has used it.

If your boards are already NAILED down… You’ll have to un-nail them, do the flashing, and then screw them back down. Otherwise you’ll have to create a roof that is hung below the joists. There are some products on the market for this, but they aren’t very cheap.

@Andy Andy, I am in the same situation. I think the ideas about flashing the joists are fantabulous. But how do we accomplish this when your deck boards are in place? Very difficult to work from below. Did you have any ideas or recommendations?

OK… I converted my 3ds max 3D models into Google sketchup format and update this post.
Go to the top of this post and you can find the link to download the sketchup file.
Let me know if that helps!
