My plans are to make a room about 15x18 out of block then finish the inside with knotty pine, it will have a dehumidifier in it that will drain down a exsisting waste pipe. As far as safes go I have 2 40 gun safes now and what a pain getting to the ones in the rear and I find no matter how careful you are getting them out they always get dinged. The room will also have my reloading bench and a closet to store all my ammo..
I have been looking at some doors on the net, Sportsman steel and browning..
Fort Knox sells complete concrete vault rooms whatever size you want. Might be worth looking into so you don't have to build your own...
