I'm currently in the process of setting up a gun room in a spare bedroom. I don't have anywhere else in my house to put a gun room. My house is built on a large crawl space that's about 6.5 feet tall. The main level is master bedroom, living, laundry, and kitchen. My upstairs is 2 bedrooms, sitting area, and bathrooms. My main concern is weight limits in a upstairs room. I don't have a gun safe anymore because the only place I could put it was in the garage and I was worried about humidity cause I live in GA. So my question is how much weight can I safely put in a upstairs bedroom. Ill have about 2 dozen 50 cal ammo cans full of ammo, a work bench(150lbs), tool box full of guns and loaded pistol and rifle mags( 350ishlbs) plus some other odds and ends. I'm probably over thinking this a little bit, but better safe than sorry.
