A lot has changed since December 21, 2012, when around 10% of people falsely believed the world would end.

The effects of climate change have become more frequent and severe, threatening vulnerable areas with floods, hurricanes, and extreme heat. Machines have become more intelligent, leading some to worry about a technological overthrow of society. And the possibility of global nuclear warfare looms even larger, with North Korea continuing to advance its nuclear weapons program.

Predicting one of these unlikely doomsday scenarios may be impossible, but planning for them isn't if you're a member of the 1%. Take a look at the "billionaire bunkers" that could house the superrich during an apocalypse.

Amid growing threats to the safety of our planet, a small group of elites  have started to discuss their doomsday plans over dinner.

In some cases, these conversations have prompted wealthy individuals to purchase underground bunkers to shelter themselves during a disaster.

"Billionaire bunkers" don't need to be built from scratch.

A few companies now manufacture luxury doomsday shelters that cater to superrich clientele.

The Vivos Group, a company based in Del Mar, California, is building a "global underground shelter network" for high-end clients.

Their fanciest compound, known as Europa One, is located beneath a mountain in the village of Rothenstein, Germany.

The shelter was once a storage space for Soviet military equipment during the Cold War, according to the company's website.

In exchange for purchasing a bunker, residents are provided with a full-time staff and security team.

The property is designed to withstand a close-range nuclear blast, airline crash, earthquake, flood, or military attack.

A typical living quarters has two floors. On the lower level (shown below), there are multiple bedrooms, a pool table, and a movie theater.

Each family is allotted 760 square metre, but has the option to extend their residence to 1,600 square metre.

This sample movie theater can fit a family of five.

The bunker includes communal spaces, such as a pub for tossing back a few while the world comes to an end.

Or a chapel for sending prayers to the rest of humanity.

When doomsday arrives, the company envisions residents arriving in Germany by car or plane. From there, Vivos will transport them via helicopter to their sheltered homes.

The full underground structure stretches nearly 70,000 square metres.

There are only 34 private living quarters, so space is limited.

But the price will likely preclude most people from buying. Private apartments start at $2.5 million and fully furnished, semi-private suites start at around $40,000 a person.

If billionaires can't find space at Europa One, there's also xPoint, a compound in South Dakota that's almost the size of Manhattan.

xPoint was originally built by Army engineers.

The compound's location near the Black Hills of South Dakota makes it relatively safe from flooding and nuclear targets, according to Vivos.

xPoint comes with its own electrical and water systems, so residents can survive for at least a year without having to go outside.

The entire compound consists of 575 bunkers, each with enough space for 10 to 24 people.

Each bunker is around 670 square metres.

The bunkers start at $35,000, but residents will also have to pay $1,000 in annual rent. That'll likely require some savings when it's unsafe to go outdoors.

The company has yet another shelter in Indiana, which can house just 80 people.

The Vivos website likens the shelter to "a very comfortable 4-Star hotel".

The communal living room has 4m-high ceilings.

Residents aren't expected to bring anything other than clothing and medication.

Vivos provides the rest, including laundry facilities, food, toiletries, and linens.

There's even exercise equipment and pet kennels.

The shelter is co-owned by its members, which makes it slightly more affordable than the company's other models.

Vivos claims on its website that the shelter is safe from tsunamis, earthquakes, and nuclear attacks.

In a statement, the company said interest in its shelters has "skyrocketed over the past few years." The website says that "few" spaces remain across its network of bunkers.

Vivos members aren't all elite one-percenters, the company said, "but rather well-educated, average people with a keen awareness of the current global events."

The Survival Condo Project, on the other hand, caters exclusively to the superrich.

The facility only has room for about a dozen families, or 75 people in total.

The facility is somewhere north of Wichita, Kansas, but its exact location is secret.

A single unit is relatively small — around 550 square metre.

As of last year, units were advertised for $3 million each. The company also sells half-floor units for around $1.5 million.

All floors are connected by a high-speed elevator.

Homeowners can venture outside, but there are SWAT team-style trucks available to pick them up within 400 miles.

Under a crisis scenario, residents have to secure permission from the company's board of directors before leaving the premises.

But conditions inside are far from unbearable. The facility comes with a gym, game center, dog park, classroom, and 75-foot swimming pool.

There's even a rock wall. Doomsday has never sounded so luxurious.
