How a Mud House in Kerala Is Helping Build a Community of Creatives


“COB” is a mixture of clay, sand, straw (or some other long strong fiber) and water,traditionally mixed by foot, in community and preferably to music (speeds the mixing). It has been and continues to be the world’s oldest, cheapest, most sustainable, healthful, durable and beautiful building material, allowing the builder(s) to quietly and happily create a personable unique home which can last 100’s to 1000’s of years and cost a fraction of conventional building.

“Cob” is the finest building material on the planet: fire-proof, rot-proof, mold-proof, rodent-proof, wind-proof, sound-proof and earthquake-resistant . It lasts forever with a good foundation and a good roof that protect it from standing water and overhead rain. It breathes and releases moisture continuously and creates a balance between outside and inside humidity and temperature so there is always a comfortable equilibrium for human beings living in cob houses.
