Andy Davis' 2,300‑sq‑ft earth‑sheltered house in Armington, Illinois, listed for $59,000 on Thursday, features hand‑picked Colorado river rock covering its ceilings, walls, and corridors.
According to the listing, Davis built the home in the 1970s to counter rising energy costs, integrating the structure into the surrounding land for natural climate control.
With a price per square foot of roughly $26, the property trades at about a third of Armington’s median rate of $77, making it a rare bargain for a stone‑lined space.
The kitchen remains unfinished, and the interior is described as a "blank slate", meaning any buyer must bring contractors to realize the five‑bedroom layout; the unique stone interior could appeal to vacation‑home investors or Airbnb operators.
The listing is already topping Realtor.com’s most popular homes list and remains open to offers until further notice.
