This underground $18M ‘doomsday’ mansion in Las Vegas has a pool, guest house, yard and beautiful views.

The reinforced concrete bunker sits 26 feet underground and comprises of about 15,000 square feet of space.

This includes a four-bathroom main house, 5,000-square-foot three-bedroom and a separate 450-square-foot one-bedroom guesthouse.

Girard Henderson built the bunker in 1978. It’s one of the multiple underground homes he built during Cold War tensions.

The underground mansion has an elevator and two staircases between its entrance and the ground level.

It also has a steel door that serves as the main entrance and security gates that protects other entrances.

Dozens of steel posts and beams reinforce the thick concrete to ensure protection from impact.

The traditional-style home includes the best decor and design that the 1970s had to offer.

The interior is decked out with a well-designed ’70’s kitchen, great room with beamed ceilings and a wood-burning stone fireplace.

There are also sliding glass doors that open to the faux outside lawn and views. 

But the most jaw-dropping aspect of the home is the “outdoor” space.

The mansion’s ‘outdoors’ contain artificial grass, various types of (fake) trees, a swimming pool, fountain and BBQ.

Additionally, the outdoor features lightings that simulate night and day, with views of mountains, valleys and woods.

According to TopTenRealEstateDeals.com, people are trying to find the best and safest place during the COVID-19 outbreak. And this bunker offers the “perfect place to ride out the 2020 pandemic and have fun doing it.”

As Forbes reports, the mansion also has a sauna, putting green and a nightclub with a bar and dance floor.

It features two Jacuzzis and waterfalls as well.

After Henderson’s death, in 1983, his widow built a townhouse on the land above the bunker. And the house is part of the property.

The current owners have added some essentials, including repeaters that allow cellphone reception, cable, and internet.

They’ve also upgraded air-conditioning units (you need to have plenty of fresh air down there!), among other infrastructure improvements.

You don’t need a garage underground, but there’s an additional casita for guests. There’s plenty of room to park on the surface. You can reach the underground level by stairs or elevators.

So if the property won’t protect against a full-on attack, what will owners do with the place?

The president for the Society for the Preservation of Near Extinct Species, Mark Voelker, has some ideas.

He suggests owners could iron out zoning issues and use the banker for special events.
