I have an uninsulated storage shed that needs a door before winter. I've read threads here on the forum about this and I’m a bit wiser than before, but I still want opinions on my planned solution. What do you think about simply covering a 21 mm construction plywood with vertical panel boards? With this solution, I don't see any point in a "z-frame" since the plywood stiffens the door. I’m thinking of three horizontal battens for nailing the panel to.
Seems like a reasonable solution, but if you're going to use extra studs to attach on the back anyway, why not make a traditional door with classic reinforcement on the back?

Okay, I understand. But I'll probably go with plywood since it seems like a simpler and better way to stiffen the door. The reason I was thinking of a couple of horizontal beams is because it feels weak to just attach the panel solely to the plywood, but maybe it works?
Regular construction plywood will probably not last as long as a traditional door. As an exterior door for an unheated storage space, it will get quite damp and might even get wet occasionally, and plywood can't withstand that without eventually delaminating.
In my opinion, a traditional door is both better and cheaper.
The plywood board is basilit treated which should extend its lifespan, though I have no idea by how much. Additionally, it costs me no money, so the price doesn't matter.
Is there no one who has built a similar door and has experiences to share?
Build the door as you have planned and paint it with a color so that moisture doesn't penetrate so easily. If it later starts to warp or begins to break in some other way, you can always reinforce it with a Z of boards on the inside.

A little suitable adhesive on the panel depending on the treatment of the plywood gives it strength and stability, but it will be heavy with a 21mm board + an equally thick panel.
