An enormous 8,000-square-foot fortress set on 40 acres of land in Nevada's sagebrush-dotted high desert, a 2.5-hour drive from Las Vegas, is selling for $950,000.

The so-called Hard Luck Castle with four-bedrooms and three bathrooms is an extraordinary and admittedly quite odd architectural wonder with a fantastical design you'd expect to find on the set of an apocalyptic science-fiction film—think "Mad Max."

Its concrete walls are 16 inches thick and wrap around the circular structure with a central staircase taking you to all four floors and a solarium encased in glass for stargazing.

"It's absolutely amazing," says listing agent Jake Rasmuson of Bishop Real Estate. "You have to picture the middle of Nevada...your views are completely uninterrupted.

The main house is comprised of 22 rooms including a wine cellar, a theater and game room, a viewing deck and a fountain room. There are also two working 1920s pipe organs that resonate throughout the halls when played.

A builder from Southern California, the owner chose the town of Gold Point (pop. 6) in Esmeralda County for his dream home due to its privacy, lack of building codes and few laws on private land. He spent $3 million and 12 years to complete his plan, and now he's ready to move onto his next adventure.

"He built it all himself with help from friends ," says listing agent. He's a guy who can fix or do anything. He's an amazing craftsman."

He added: "He's ready to give up the property. Purchase a boat and start a new chapter in his life."

The property is off-the-grid with self-sustained energy systems using solar and wind and a 4,000 gallon water storage tank has rain catchment. There's a detached 600-square-foot workshop equipped with tools for working on cars and steel fabrication and a remodeled miner's cabin with a new bathroom and kitchen.

A productive yet dormant gold mine with a "serviceable" mine shaft is also included. It was shuttered after World War II, but allegedly still contains gold.

"In a lot of ways, it's a 'doomsday prepper' dream home...extremely self-sustaining and secure."

That said, Rasmusson says he could also see an interested buyer might be "an astrologist, an artists, a writer, a musician, a poet, someone who really wants peace and quiet and wants two pipe organs in their home" because the organs and everything else except the owner's dog and truck are included in the sale.
