The bunker is primarily made up of four large rooms that all have 16.5ft ceilings. As you enter, you reach the smallest room. Then you get to the second biggest room, and turning to the right from there is the largest room. Circling back from there, you come to a smaller room at the back. There is also a mezzanine and a pump room and a small fan room. The first room was originally an office space, the second largest room was the telecommunications equipment room and the largest room was the battery room. That one room is 1,700 square feet.
There is only about 4ft of earth above us, but the whole structure is built with two feet of reinforced concrete, and I have heard that rebar is as thick as a human arm. It’s also electromagnetic pulse (EMP) shielded; the whole structure has a copper mesh around it in case there was an EMP burst, in order to protect the electronics. We have a 3,000lb blast door at the front, a 2,000lb blast door at the back and an escape hatch. The escape hatch leads to a full stairwell that you can go up and leave through. My understanding is that the bunker can withstand a near-miss nuclear explosion. As long as we are not vaporized in the crater, we should be OK.
Interesting, but no thank you. This isn’t for me. I’m not opposed to the heavy doors, EMP shielding, and the four feet of earth is acceptable. I don’t need or want 6,000 square feet to take care of. Nor would I want to have to spend hundreds of thousands to remodel it into something resembling a reasonable floor plan. The escape hatch would be kind of nice though.
