Cob

Cob COB is the building strategy I studied in 1996 with the wonderful Cob Cottage Company. It is simply sand, clay and straw.  More details below. Here is a picture of that first course, and the project we worked on for 3 weeks.  I am the short one, 2nd from the upper left. This was my start.  ( I don’t know where this picture went, alas)

Since then I have built with cob, co-creating numerous projects.  Below is a Cob Garden Wall being constructed on the Hobbit Sauna. A group of Waldorf 3rd grade students were participating that day.

Also on site are several Earth Ovens and Rocket Stoves built of cob.  It is a wonderful local sculptural strong material.

What is Cob? 

(from the cobcottage.com Website)

Earth is probably still the world’s commonest building material. The word cob comes from an old English root meaning a lump or rounded mass. Cob building uses hands and feet to form lumps of earth mixed with sand and straw, a sensory and aesthetic experience similar to sculpting with clay. Cob is easy to learn and inexpensive to build. Because there are no forms, ramming, cement or rectilinear bricks, cob lends itself to organic shapes: curved walls, arches and niches. Earth homes are cool in summer, warm in winter. Cob’s resistance to rain and cold makes it ideally suited to cold climates like the Pacific Northwest, and to desert conditions.

Cob has been used for millennia even in the harsh climates of coastal Britain, at the latitude of the Aleutians. Thousands of comfortable and picturesque cob homes in England have been continuously occupied for many centuries and now command very high market values. With recent rises in the price of lumber and increasing interest in natural and environmentally safe building practices, cob is enjoying a renaissance. This ancient technology doesn’t contribute to deforestation, pollution or mining nor depend on manufactured materials or power tools. Earth is non-toxic and completely recyclable. In this age of environmental degradation, dwindling natural resources, and chemical toxins hidden in our homes, doesn’t it make sense to return to nature’s most abundant, cheap and healthy building material?
