The rammed earth houses on Rosemary Road in Mount Olive, Alabama, were built in the 1930s. They were constructed with dirt, taken from the site, which was mixed with red-rock aggregate and tamped between wooden forms. The homes were built as part of a New Deal Resettlement Administration homestead community. The surprisingly sophisticated one-story houses, designed by architect Thomas Hibben, are reminiscent of the low-slung, prairie-style houses designed by famed architect Frank Lloyd Wright. The government was not sure of the lasting quality of these rammed earth homes and required that they be located at the back of the project, so as to not be too visible if they collapsed, but all the rammed earth houses of Mount Olive are still standing today. Images of the buildings at the time of their construction can be found here.
