Las Vegas has no shortage of spectacle, but even in a city built on surprises, this one takes things underground — literally.
Just a few minutes from the Strip, a seemingly ordinary home conceals one of the wildest properties ever built in the U.S.: a sprawling 14,620-square-foot subterranean estate that looks like it was frozen in time in the ’70s.
Known as the Underground House, this $8.5 million listing isn’t just another retro throwback. It’s a full-on Cold War–era compound, created in the 1970s by businessman Jerry Henderson and architect Jay Swayze as part of a vision for secure but stylish “Atomitats” designed to withstand nuclear threats.
While most fallout shelters were built for survival, this one doubles as a 1970s fantasyland, complete with hand-painted murals, faux landscaping, and even a programmable sky that simulates sunrise and sunset.
Two homes, one address

The property at 3970 Spencer Street in Las Vegas actually includes two separate living spaces. Above ground sits a conventional two-bedroom, two-bathroom home.
Below ground, you’ll find a much larger setup: a 4,100-square-foot residence with three bedrooms, four bathrooms, and a casita — all connected within the subterranean compound. The property is listed with Holly Erker of IS Luxury.
A traditional two-story home above

On the surface, you see a traditional two-story house with a four-car garage, sitting quietly on an acre of land.


A 14,620-square-foot underground time capsule
But descend 26 feet down, and the real show begins: a 14,620-square-foot underground oasis with its own residence, sprawling entertainment areas, and a vibe that blends sci-fi imagination with Vegas showmanship.



With an artificial sky on demand
One of the most surreal features of the Underground House is its programmable lighting system.
The “sky” cycles through daylight and twilight, giving the illusion of natural rhythms even when you’re 26 feet below ground. It was a futuristic concept when installed in the ’70s — and it still feels otherworldly today.


And murals, trees, and vintage flair
Step inside and it’s like opening a perfectly preserved time capsule. The interiors boast custom hand-painted murals of mountain landscapes, sculpted faux trees, retro furniture, and pastel finishes.
While it may not be everyone’s idea of modern luxury, the preservation is remarkable — more like walking into a living museum than a typical home.


Technically, a subterranean paradise with everything built in
The underground world doesn’t skimp on amenities. It comes complete with a swimming pool, putting green, two saunas, a dance floor, a bar, a theater, and multiple lounge areas. The design was all about comfort and distraction, allowing residents to forget they were sealed off beneath the earth.


Including vintage 1970s interiors with unmistakable elements
The decor has been frozen in the ’70s, with quintessential elements like busy drapes and valances, fringed sofas, plush seating, and even the obligatory high-heel-shaped chair making an appearance.





An American original
Part Cold War relic, part Vegas oddity, the Underground House stands alone as one of the country’s most unusual residences.
Whether the next owner embraces its kitschy retro appeal or transforms it into something new, they’ll be taking stewardship of a property that’s as much about history as it is about real estate.
