Dwellings in Jericho, which were built in 9000 BC of mud brick, still stand today as testament to the longevity of earthen homes. Cob has also been popular in the UK and Ireland as their soils have a high clay content. Thousands of old cob dwellings are still in use as residences in the UK.
Cob Homes Are Simple And Sustainable
Combine two buckets of clay, three buckets of coarse sand (if your subsoil already has the correct proportions of clay, silt and sand better yet), add some water and straw, stomp on that with bare feet for a bit, form into lumps (cobs) for ease of transport, then start building.
If your subsoil is appropriate, your cob building could be the utmost in sustainability, if you build with local stone and use no machines, there would be no transport of building materials and no fuel use. Plus your home will most certainly not pollute the environment as it will simply return to the soil from which it sprung (many years down the line). You can also reuse cob again and again, take down a wall and then reuse the same cob to build a new wall.
In cob building, a home’s boots (foundation) and hat (roof) are extremely important, as cob should not be exposed to excessive water.
The World’s Most Amazing Cob Homes

A permeable finish is necessary to allow breathing and to avoid damp walls. Clay based or lime based finishes are best. Decades ago many in the UK coated the exterior of their old cob dwellings with a cement render. As the render was compromised with time, water that got into the cob had no avenue for escape and the trapped water slowly ate away at the cob. Cob walls need to breathe.cob-solutions.co.uk

Gary built ‘flimsy’ plywood forms to hold the cob in place. The base of the building is intentionally wider than top of the wall. Instead of adding sand he used just clay and straw in his mix.placepatterns.org

Hilde’s Cob house built in 1999 during a 3 week workshop led by Ianto Evans and Elke Cole. The roof was put on that fall and the following spring the interior finishing was completed by Tracy, Elke and Patrick. Hilde’s project was the first cob fully permitted as a house in Canada. The roof is totally load bearing on the cob walls. The house is 600 sq.ft on 2 floors and is fully plumbed and wired. Finished cob and roof construction costs were approximately $56,000.cobworks.com

Oh my goodness. I love how full of pictures this is. I’m going to be daydreaming for hours, imagining which house I’d like to live in. Cob houses are so beautiful and romantic (I mean, in addition to all of their practical and sustainable functions). Thanks for all of this dreaming-fodder – it injected a little bit of fun into my day.

I’d would like to build a cob home in the state of WA. Is that possible to build in that area? I have so many ideas… But, are there companies that specialize in doing the building?
Kane Jamisonsays
Yup, cob is popular in the Pacific NW. If I understand correctly it was common in the UK which has a similarly wet climate. The classic refrain is that you need to give the structure “a good hat and boots”, meaning, it needs a dry and sometimes slightly raised foundation, no water draining towards the structure, and a great roof with wide overhangs to keep water away from the walls.
I don’t personally know any cob builders in WA, but there are a number of natural builders, many of whom work in cob and other approaches like earthbags. I’d start by searching “cob builders washington” and start working your way through the names/companies you find. Good luck!
Stan Barlogsays
Fantastic(al) designs. Very inspiring. I wish there were pictures of the interiors of those structures as well.
