Climate & Environmental Considerations
"In Los Angeles, cob construction must address seismic activity and high UV exposure. The structural design incorporates reinforced foundations and internal pinning to meet California's strict earthquake safety codes, while lime-wash finishes protect the earthen walls from the intense Southern California sun and occasional heavy rainfall, ensuring long-term durability and thermal performance."
