> A simple example is in my previous home when I had a section of the master bedroom closet partially walled around a Class C TL-30 rated safe, and the room partially reconstructed with ballistic armor in the walls and a vault door, to turn it into a safe room for valuables + home protection.
But... why? This does not seem like a typical use case.
It's pretty much a rite of passage as internet millionaires to have a safe room with 9,000 lb safes isn't it? Who doesn't have a house with a ballistic safe room? I'm just trying to put the helicopter landing pad on my house and the damn HOA won't pass my building plans. I think I'm going to have to buy a bunch more houses so I can get more votes. #noNimbys
You're free to churn butter by hand using a toothpick in the comfort and privacy of your own home, but I wouldn't take complaints about toothpick integrity from someone doing that seriously.
There are much better arguments against shitty, compromised concrete than 'I need to park a semi-truck in my bedroom closet.'
There are much better arguments than "I want to blow up a bomb in my house" as well. Oh, and there are better arguments than "I want to dig the house out of the ground and drop it from a great height".
One example of a reasonable argument is: "I want to put a very heavy safe on the floor, which works fine when it's normal concrete".
Don't forget the other reasonable part, testing that 50 caliber machine guns can't penetrate the safety of your home walls. That's pretty normal too, right?
To be fair, someone building a panic room/closet for personal protection makes a hell of a lot more sense than buying a gun for a similar purpose.
Unless your threat vector is 'A cartel/the Mossad/the FBI really, really wants you dead', a cellphone and a room with no windows and a heavy door that locks from the inside will solve 99.9% of that problem, without all the problems that guns bring.
