Texas Cob Home Shows That Earth-Built Living Can Be Modern and Comfortable

Sustainability advocates Arielle Crawford and Simon Gonzalez built a 500-square-foot cob home on five acres in Texas using non-toxic earth materials (clay, sand, straw, lime plaster). They founded Texas Cob to design, build, and restore earthen homes and offer cob-building courses through their nonprofit. The year-long project cost about $160,000 (70% labor) with 2-foot-thick walls that provide strong energy efficiency; the home includes AC, electricity, and plumbing, and permitting was eased by local earthen-building rules (they bypassed septic with a compost system). The couple emphasizes that cob homes can be modern, customizable, and insurable, challenging the Hobbit-house stereotype and highlighting lime plaster or limewash as practical finishes for wider adoption.
