A unique underground home in Armington, Illinois, is attracting attention for its unusual design, fascinating history, and affordable asking price. Built in 1977 by Andy “Caveman” Davis, the approximately 2,300-square-foot property was designed to reduce energy costs by using the surrounding earth to help regulate indoor temperatures. Now listed for $59,000, the home offers a rare opportunity for someone willing to take on a major renovation project.
The house stands out because of its rock-covered walls, arched hallways, and distinctive architectural details. Davis and his family collected rocks during annual trips to Colorado, incorporating them into the home’s interior to create a natural, cave-like atmosphere. Round windows and other unusual features give the property a character rarely found in traditional houses.
One of the home’s most memorable details is its bathtub surrounded by rocks, which adds to the feeling of living inside a natural cavern. The earth-covered roof and concrete exterior also reflect the original goal of creating a more energy-efficient living space. Rather than following conventional architectural styles, the house embraces its surroundings and turns natural materials into its main design feature.
Despite its charm, the property remains unfinished and needs significant renovation, particularly in the kitchen and other interior areas. Its potential five-bedroom layout gives future owners several possibilities, whether they want to create a unique private residence, a vacation rental, or another investment property. However, the low asking price may be only the beginning, as restoring such an unconventional home could require considerable time and money.
For buyers who appreciate unusual architecture, the Armington property offers something different from an ordinary house. Its combination of personal history, rock-covered interiors, and underground design makes it a distinctive project for someone with imagination and a willingness to transform an unfinished home into something special.
