$70K underground Missouri home from 1976 survived F4 tornado, still hidden
Built in 1976 for $70,000, a remarkable underground home in Springfield, Missouri, was designed to blend into the hillside while providing strength and energy efficiency. Nearly 50 years later, the concrete residence remains largely hidden from view and has an extraordinary history, including surviving a devastating F4 tornado that struck the neighbourhood in 1990.
In Springfield, Missouri, a hidden underground home from 1976 survived an F4 tornado, remaining largely concealed beneath the hillside. Built by architect Dennis Spencer, the concrete structure was engineered to blend into its surroundings, rather than stand out. The house, constructed for $70,000, occupied a sloping, north-facing site and used post-tensioning technology to increase its strength and durability.
Despite its unassuming exterior, the home featured skylights and large windows to bring natural light into the interior spaces, creating a seamless connection between the living areas and the landscape. Following the 1990 tornado, the underground house emerged largely intact, demonstrating the effectiveness of Spencer's design in providing shelter and protection during severe weather events.
