"It's a good time to be in the bunker business." That's how the Washington Post frames its latest report on the booming world of high-end doomsday bunkers, where worries about grid failures, pandemics, cyberattacks, nuclear fallout, and even artificial intelligence are driving demand—especially among the wealthy. Veteran builder Brian Camden says it's less about secret spas and shooting ranges and more about the unsexy math of survival: air in, sewage out, power on, and how long people can realistically stand to live underground. "Every request, no matter how basic or extravagant, runs into the same stubborn questions," the Post notes.
The market now ranges from $55,000 leased shells in a South Dakota "survival community" to multimillion-dollar, custom concrete fortresses with gyms, theaters, rock-climbing walls, and saltwater pools. But engineering around humidity, ventilation, waste systems, and human behavior—right down to "anti-mutiny" safeguards and a handyman on standby—can turn fantasy into a logistics slog. And there's a philosophical question lurking: Are private bunkers a sign of resilience, or just another symbol of concentrated wealth in a shaky world? For the full dive into the bunker boom, more here. (In Nova Scotia, an underground nuclear shelter has been transformed into a luxury hotel, while in South Dakota, there's that whole "luxury survivalist community" mentioned earlier.)
