I don't mean to rain on your parade too, but how mobile will this be? Is it now part of the house? How hard to disassemble and return the room to normal if you were moving?
I know you guys mean to be in the house a long time but life happens sometimes. I don't know how much money (or headache) you'll save trying to build one instead of just throwing down a little more on a large safe that can come with you.

When you are smoking and keep the lid closed and closing the vents, it is preventing airflow, all the moisture becomes trapped in your metal box. Give it some air, and some of the moisture can escape. Same principal. Do you want your guns moist?

You can have a closed space, especial if entering air is relatively moist, just need some movement and temperature high enough to prevent condensation.

Love the idea of this and have thought about it before. I didn't even think about air movement. Great stuff.

I had no intention of being able to take it with me. Essentially its a big empty spot in my master closet that the previous owners had a sauna in. I figired if done well, shouldn't be an issue come selling time. Dan, I'm not againt wire mesh, I was just hoping for good fire protection, and kaybe more than jist smash and grab protection. As stated before, I'm on a slab. So would I be able to do a mesh ceiling, for air flow? I guess I'm having a hard time understanding the problem if a guy just kept some sort of heat source and/or dissicant in there.

Yes, you can do a mesh ceiling, as basically it's just really beefed up chicken wire. You want to think about your fire resistance when it comes to venting. That's why a jumper vent that goes into a conditioned space is nice.
If you have forced air, look at putting in a small supply line. Then, with the jumper vent you will keep equal pressure in the room and perform actual air changes which will decrease humidity and stagnation. I'll draw something up later today when I am on CAD and maybe give you a better visual.

Ok, here is what I have. The first image shows the wall (and ceiling) construction.  Then, we have the Jumper Vent. All it is, is a floor vent on the wall and a small duct connecting it to another vent on the other side of the wall. Allows air to flow to and from the space, yet small enough to keep people from using it as a break-in point. When you heat the room (with forced air), it will pressurize the room, pushing all the old air out of that vent, then as the air cools, it will pull back in the air from the other side, basically helping to perform an air exchange. If you choose to run a baseboard in there, that's fine too, it will still seep back and forth, but if you don't plan on going in the room for a couple of days, it wouldn't hurt to run a fan in there as well.

Kinda out of the box but you could look into ICB's and hang the drywall on the inside of that. Only peoplem would be getting it to the current roof line.

I guess I'm having a hard time understanding the problem if a guy just kept some sort of heat source and/or dissicant in there. a very very small vent in the ceiling and a small rv dehumidifier will do the trick inside a small room. Just do not add too much heat. I have seen a lot of condensation inside boats that did not vent and only added a heater to the inside. this dehumidifier will work well, but probably overkill for your application. Look for one that is a similar make for half the space. It will compare to adding an incandescent bulb to the room but much more safe.. https://www.amazon.com/Ironwood-Pacific ... humidifier

i bought a house with a vault/gun room already built in 6 inch concrete walls on all sides including ceiling, sitting on a slab that was poured just for this vault, rest of the house is on a foundation  heavy duty metal door   previous owner's gun rack  i have just a small safe heater plugged in and inside the safe, rest of the room is heated by a regular light bulb that is always on. no humidity issues from September up to today no jumper vent either
