A Home Unlike Almost Anything Else in Illinois

Located in Armington, Illinois, this remarkable underground residence was built in 1977 by a man named Andy Davis, who was reportedly known as “Caveman” Davis.

His unusual nickname seems especially appropriate when you consider the home he created.

At a time when many families were concerned about increasing heating and cooling expenses, Davis decided to experiment with an alternative approach to residential construction.

Instead of building a conventional house entirely above ground, he designed an earth-sheltered residence that blended into its surroundings.

The idea was relatively straightforward.

Because underground temperatures generally fluctuate less dramatically than outdoor air temperatures, carefully designed earth-sheltered homes can benefit from natural insulation and reduced heating and cooling demands.

However, their actual energy efficiency depends on factors such as insulation, ventilation, waterproofing, and construction quality.

The Extraordinary Detail Hidden Inside

While the exterior is unusual enough, the interior contains an even more personal architectural feature.

According to the property’s listing, the ceilings and arched corridors incorporate river rocks collected by the Davis family during annual trips to Colorado.

Imagine gathering stones during family vacations and eventually using them to decorate the home where your family would create memories for years.

These natural materials give the residence a distinctive cave-like character that would be difficult to reproduce in a conventional house.

The combination of curved passages, stonework, and underground construction makes the property an unusual example of experimental residential architecture.

How Much Does This Unique Home Cost?

Here’s another detail that makes the property interesting.

The house was listed for just $59,000 in October 2026.

According to the real estate listing, the property offers approximately 2,300 square feet of space and a potential five-bedroom, two-and-a-half-bathroom layout.

But there’s an important catch.

The residence is being marketed as a restoration opportunity rather than a fully finished, move-in-ready home.

A buyer would need to evaluate the property’s condition and the costs involved in completing renovations.

The listing also mentions two separate electric meters, potentially making the property suitable for conversion into two living units, subject to local requirements.

Two new circular windows are reportedly included with the sale.

Would You Actually Live Underground?

For someone who loves unusual architecture, this property could be a fascinating renovation project.

Its distinctive construction offers opportunities for creative interior design, while its history gives it a personality that many modern houses lack.

But underground living also presents challenges.

Proper ventilation, natural lighting, drainage, and moisture control are especially important in earth-sheltered buildings.

Anyone considering such a property would need a thorough professional inspection before making a purchase.

Nevertheless, the home demonstrates how creative thinking can produce something extraordinary.

Nearly five decades after its construction, Andy Davis’s unusual house continues to attract attention.

What began as one man’s attempt to reduce energy expenses became a remarkable piece of architectural history.

And perhaps that’s what makes the property so fascinating.

It isn’t simply a house built beneath the ground.

It’s a reminder that sometimes the most memorable homes are created by people willing to challenge conventional ideas.

Would you live in this underground house for $59,000, or would you prefer a traditional home with plenty of windows and sunlight?
