$70K underground Missouri home from 1976 survived F4 tornado, still hidden

When Tim and Monica open the front door of their home in Springfield, Missouri, there is little to suggest that a house is hidden beneath the hillside outside. Only a small corner of the structure is visible from the road, while much of the home disappears into the earth.The unusual underground residence was recently featured by architecture and design-focused YouTube channel Kirsten Dirksen, offering a look inside a home that was designed nearly five decades ago around the idea of becoming part of the landscape rather than sitting on top of it.Built in 1976 by architect and builder Dennis Spencer, the house occupies a sloping, north-facing site in Springfield. Instead of treating the difficult orientation and hillside as obstacles, Spencer incorporated them into the design, creating a concrete structure that is largely buried beneath earth and vegetation.For Tim and Monica, the unusual design has become an everyday reality.
