Hidden among the greenery of Armington, Illinois, is an unusual earth-sheltered home built by Andy “Caveman” Davis in 1977. Inspired by energy-conscious design trends of the 1970s, the property combines natural stonework, rounded architectural details, and a grassy roof that blends into the surrounding landscape. Spanning approximately 2,300 square feet on a 0.33-acre lot, this distinctive residence offers a striking alternative to conventional home design.

One of the home’s most memorable features is its extensive use of river rock and stone arches, with some stones reportedly collected by Davis and his family in Colorado. Rounded windows and handmade details add to its unique character. The property is described as having five bedrooms and three bathrooms, along with additional architectural features that reflect its unconventional design. However, the home requires substantial renovation, making it a potential project for buyers interested in restoring distinctive properties.

Several important features remain unfinished, including the heating and cooling systems, kitchen, electrical work, and storage areas. Prospective buyers would need professional inspections, realistic renovation estimates, and guidance on local building requirements before proceeding. Because the structure is partially covered by earth, particular attention should be given to drainage, moisture protection, ventilation, insulation, and structural stability. Despite these challenges, the property offers an opportunity to restore a remarkable piece of architectural history and transform its natural materials and distinctive design into a personalized living space.
