Who isn’t planning for the apocalypse, be it nuclear, plague, zombie or alien in origin? Now you can do it like a boss.

The best part of a survival bunker is installing a thick glass portal to watch your neighbors begging to be let in after spending all those years laughing at you.

Now you can do all that and more in style with these luxury condos that can withstand a nuclear attack.

When Tyler Allen agreed to fork over $3 million in cash for a luxury condominium near Concordia, Kan., he wasn’t attracted by the indoor swimming pool, 17-seat movie theater, or hydroponic vegetable garden.

The real selling point of the 1,820-square-foot apartment: It will be buried 174 feet underground in a decommissioned missile silo sturdy enough to withstand a nuclear attack.

Mr. Allen, a 45-year-old Orlando, Fla., sports bar and nightclub owner, insists he isn’t a “tinfoil hat-wearing” type preparing for the end of the world.

Rather, he cites growing security threats—such as a global health pandemic, cataclysmic weather and terror attacks.

“There’s a Camp David for the president,” he says. “If you’re at a certain level where you can afford it, you can get that, too.”

The so-called Survival Condo complex boasts full and half-floor units that cost $1.5 million to $3 million each. The building can accommodate up to 75 people, and buyers include doctors, scientists and entrepreneurs, says developer Larry Hall.
