The construction process involves layering and sculpting the cob mixture, allowing for creative designs and organic shapes. Cob houses are often eco-friendly and sustainable, as they utilize local materials and can be built with minimal environmental impact. Many people appreciate their unique aesthetic and natural insulation properties.
