I built a gun room in my basement. I should have done it when built the house as the did the house plans myself and built it my self. Since the house was all ready finished and I was doing this on a budget and already had a large gun safe, I sectioned off a 10 x 10' corner.
I framed it with 2x6's, drilled through the center of each stud at 6" intervals and into the poured concret walls; drove 10' 5/8" rebar through the studs from the floor to the ceiling at six inch intervals anchoring them into the drilled walls. Covered each side of the studs with 5/8" plywood then 5/8" fire rated drywall, and 5/8" drywall on the ceiling. Our house has infloor heat and ceramic title, so the floor above is covered with 2 3/8" of light wieght concret, morter and title. I built the door frames with 3 2x6's sandwiched together with the rebar going through them at the 6" interval.
The door is wood, I purchased at Menards two solid oak doors that had water damage. I routed them to insert rebar vertical and horizontal and laminated and bolted them together. From the out side the door looks normal, but it is about 3 1/2" thick and weighs close almost 100 pounds. It is mounted with hinden mortised SOSS security hinges suitable for 500 pounds doors, purchased off E-bay for $40.00. I special ordered two seven pin deadbolt security locks because of the thickness of the door. They keys stay in the lock when opened so two keys are required to open the door. The room will eventually have a motion detector alarm. I have a dehumidiier in the room tied into the house drainage system. This isn't burgler proof, but no smash and grab thief is going to get into it without serious tools, only to find a large gun safe to contend with.
