This cob shed, complete with a green living roof, was built as part of a demonstration project at the City Farmer Demonstration Garden in Vancouver, B.C.. Cob is an ancient building technique that uses clay, sand, and straw mixed with water to create an adobe-like material. It doesn't refer to "corn cobs", but rather "cobs" of moist earth or clay. Cob building is considered a sustainable building technique that while made from inexpensive materials, is labor intensive. www.cityfarmer.org
