Cob is an age-old method of building that can be used to create very unique organically-shaped structures. This particular example, called the Cob Cottage, is situated on Mayne Island, a quiet and laid-back locale in the Gulf Islands of British Columbia. It was reportedly the first cob house in Canada to go through the building permit process.
Cob uses a mixture of clay, sand, straw and water to form load-bearing walls. Cob structures are built by hand with the mixture laid in layers and allowed to dry. This process lends itself to creating structures with curved walls, rounded openings, built-in display niches, and sculptural decoration. Building with cob requires a lot of physical labor but the materials are cheap, so it is one way to get a very low-cost house as long as you don’t pay someone else to do the work.
