Natural Building with Earthen Floors

Learn about the benefits of earthen floors and how to install them yourself.

Like the sculptural cob fireplace surround, the floor in Sudip Biddle and Rosalind Wu’s straw bale home in Pagosa Springs, Colorado (built by Kelly Ray Mathews) also serves as a thermal mass for storing heat and moderating temperature fluctuations. Note the use of a stone under the stove, where people might be tempted to split firewood; an earthen floor could be damaged by high-impact activity.
