Residents can enjoy both their private chambers and communal areas, which includes a luxurious pool deck.

When it comes to the end of the world, underground shelter company Vivos is betting that it's better to be safe than sorry.

The Vivos Europa One shelter in Rothenstein, Germany, claims to be the world's largest and safest underground survival bunker. It's also one of the fanciest. Available by invitation only, a spot in the bunker will set future residents back about $5 million each. Buyers can then have their chambers decorated and customized to fit their preferences.

Once it's complete, the massive bunker will be set to protect against everything from natural disasters to war.

Originally built by Soviets during the Cold War and used as a fortress for military equipment and munitions, the incredible 76-acre property was recently revealed by Vivos founder and CEO Robert Vicino.

He told Business Insider that the opportunity to buy a space in the massive Europa One bunker is being marketed exclusively to "global industrialists" and billionaires, though his company also constructs underground shelters for those on a slightly tighter budget.

"We don't know when 'the accident' is going to happen. For those who haven't secured a solution yet, it's already too late," Vicino said to Business Insider. "It's expensive, but it's an investment in your life and in real estate."
