Cob construction is a natural building method that uses a mixture of clay, sand, and straw to create sturdy walls. This technique has been used for thousands of years and is known for its thermal mass, which helps regulate indoor temperatures. Cob structures are often sculptural and can be shaped into various forms, making them unique and aesthetically pleasing. The process involves mixing the materials by hand or with machinery, then applying the mixture in layers to build walls. Once dried, cob is durable and resistant to fire and pests. This eco-friendly method promotes sustainability and can be a cost-effective alternative to conventional building materials.
