Cob

Cob is one of the most ancient methods of building with natural materials. Legs and hands are used to form masses of clay mixed with sand and straw which then are being placed one on top of the other creating that way monolithic constructions of great stability. The word cob is an English one that means small ball.

Having a histroy of thousands of years, cob has been used until the middle of the last century in England, where one can find 500 years old houses built this way. Some of its advantages are the construction rigidity, the simplicity of the tools used and the great freedom of the design. Since no straight forms are demanded the material itself leads to organic shapes: curved walls, domes and arcs. Building with cob is an experience similar to clay sculpting. Disadvantages counted are the slow building procedure and the difficulty of construction. Cob houses are very resistant to a variety of weather conditions that makes them comfortable and viabile at the most cold climates but also in dessert conditions. Cob has been used for thousands of years even to the harsh climate conditons of the British coasts of the Aleoutian Islands. Thousands of comfortable and graphic cob houses at England have been habited continuously for centuries having great current market value. The rebirth of cob started in the US, where enjoys a continuously growing popularity not only because of the advantages already mentioned above but also, because of the ability provided to the owner- builder to avoid the enormous financial burdens and commitments involving the purchase of housing.
