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.
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?

It is a pleasure to hear of your interest in cob building.
I have pulled together a number of resources in the area.
You are always welcome to visit here, where we have a thatched strawbale cottage.
I know of a few cob buildings in the region/ cold climates:
- Erin and Jim Malloy have designed and built their own efficient Earthen home in north-central Vermont. They live comfortably in their inexpensive, mortgage-free, cob home surrounded by their fruit orchard. Both Jim and Erin work in the field of energy education. Plainfield VT. (I dont know them, but an intern Zachary Davis interviewed them, and they seem to be very happy with their tiny cob home. )
- Chris Reinhart has a bale/cob structure in Indiana. He has a lot of background and may consider taking on a job, or know of someone.

- Sr. Mary Baird constructed a small cob retreat building and might give feedback on how cob is performing in Indiana.

- Dave Sebolt, Ann Arbor, an architecht
might be able to tell you how his cob and strawbale home is performing in Goshen, IN. I haven’t had contact with him in a number of years.
- Chris Fox, below, is doing natural building as a living and is great. This might be a good place to start:

Bryan Burnoski is currently based in the Midwest in a small Western Wisconsin town conveniently located one hour north of Minneapolis, Minnesota. I will be hosting various workshops focusing on cob structures using balecob, rocket stoves, earthen ovens, garden walls and benches. Projects will be ongoing and may not always be in a workshop format. I am interested in hosting people who want to learn how to build with local resources in order to create beautiful, simple and natural structures.

Go to my website Regional Natural Building page: http://strawbale.pbwiki.com/Michigan+&+Midwest+Natural+Building+Resources
There are a number of contacts and possibilities there, including a builders guild in Wisconsin.
Feel free to ask more questions.
You could consider making up an “ad” for what you want, and I could post it to my listserve. We may turn up some folks who would like to build.
There is a cob listserve which could be a good place to post this.
I would be interested to know how the process goes for you

Hi, Deanne Bedner,
Linda Smiley said I might get in touch with you about a cob cottage in the Midwest. Linda is my cousin. We are thinking about a Cob cottage at Tryon Farms in Indiana, near Michigan City. (see it on the web). Do you know if there are some examples of cob cottages near Chicago, or people we could pay to build something?
Linda will visit us in April on her way to Israel.
