Cob construction

Cob construction is a traditional building method using natural materials—primarily clay, sand, straw, and water—to create sturdy, eco-friendly structures. The materials are mixed together to form a thick, malleable "cob" that is hand-shaped and stacked in layers to build walls. Over time, these walls harden and become durable, providing good insulation and a unique, organic appearance. Cob is valued for its sustainability, low cost, and ability to be customized without advanced tools, making it suitable for many eco-conscious, artisan, and community projects.
