Cordwood sheds and cabins; sometimes known as Stackwall, Stovewood, Firewood or Cordwood Masonry.
How Cordwood Construction Works
Short lengths of debarked trees (cordwood) are laid with a mixture of mortar and insulating materials – such as sawdust or spray foam – in between the mortar. The longer the length of the logs, the better the insulation qualities. 12 inches to 18 inches is most common and wood species will also determine insulating value. On average, a 12 inch wide wall will have a 20-25 R value. Cabin by Rob Roy. Image by Pseu (Sioux) / Flickr.
A two to three foot overhang (eave) is often recommended when cob or lime putty mortar is used in place of a cement mortar. Typically the logs are not coated with a moisture barrier, but are allowed to breath naturally. By Tony Wrench at Green Hamlet in Pupki, Poland. More information is available at That Roundhouse.

Mortar Mix Possibilities For Cordwood Construction
- Lime putty mortar—lime makes the mix plastic—dates back to 400 BC: Pure lime and sand; or 9 parts sand; 3 soaked sawdust; 2 Portland; and 3 hydrated lime –
- Papercrete (paper enhanced mortar)
- Cob mix (1 part clay, 4 parts sand mixed with straw and more…)
Insulation For Cordwood Construction
- Sawdust has an insulative value of about R-3 per inch (add hydrated lime as a preservative).
- Vermiculite and Perlite are also good insulators.
Wood Types for Cordwood Construction
- Softwoods are best. Cedar has a good R-value (1.5 per inch) and is naturally decay resistant. The best softwoods: white cedar, white pine, cottonwood, poplar, red cedar, spruce or larch followed by hemlock and poplar.
- Hardwoods have a tendency to swell and crack mortar joints. If all you have is hardwood, you must split the wood and let it dry for only months instead of years, otherwise it will expand in the wall.
- For a 32′ x 36′ one story structure, you need approx 5 cords of cedar wood.

Ok guys sorry for the raw comments. In my oiinpon depending on where you live the best cord wood to use for your structure would surely be what is native around you and available free or for the work of getting it. If you live in Florida cypress wood is best or long leaf yellow heart pine. If you are from the north locust is best. if you are from the west say northern california redwood. All of these woods resist rot and fungus naturally. If you have to use soft woods you can treat it with non toxic anti freeze,borax and boric acid mixture and saturate the wood with it once a year and prevent fungus and dry rot and as a bonus it will kill termites as well. To make the solution you will use one gallon of nontoxic RV antifreeze, one pound of borax (20 mule team type) and one pound of boric acid. I have found that walmart has this roach pruf stuff for killing roaches(99% pure boric acid)for 3 bucks a bottle, powder form. In a bucket mix it all together till disolved and spray on wood till it runs off I usually go over the area twice..This stuff works..Do the research for your self if you like..Big Al
Shortly after my husband & I were married & visiting his ma in the northwoods (WI) he took me to a cordwood house. I’ve loved it then, & love it now.
Thinking it would be great for lower area of the barn I’m hoping to build.
I assume weaving some conduit into the walls while building would add electricity
I live in georgia and I am intersteded in building a cob house!
The thing that wories me is legalalty of building one.
do you know what pirmits needed?
Thank You
Zane Clark
Been loving cordwood const. for over 30 yrs.
Mis saludos y cordiales felicitaciones, a quienes propician este tipo de construcción, que a mi parecer son originales, ecologicas, limpias, acogedoras, económicas y respetuosas con el planeta.Quisiera me sugieriesen algunos libros que hayan sido escritos en castellano o algun material en el que me pueda ilustrar más sobre este tipo de construccion.

what did you use for fountation and mortor?
Where do I find building plans for any of these cabins and sheds pictured here?
Cordwood sheds are the most cost effective and classy single storey structures for wooden homes or cabins. These cordwood sheds depict traditional as well as modern looks and are used for hobbies, storage or a workshop.

hi
We made a dinning hall out of cord wood, Please take a look.

I love this page!
Just a note to thank you for the inspiration.
Have lived in Fairbanks for 40+ years so using wood in creative ways is dear to my 74 year old heart. Thanks for your work, creativity and imagination appreciation.
Hello, My Husband and I have been discussing building a house using Cob and low-impact materials and techniques. We have been doing quite a bit of research online however we have failed to find any information that pertains to our uniqe environment and climate structure. We live deep in the Alaskan interior, about 20 miles north of Denali National Park. We only have about 5 months out of the year that we would be able to avoid freezing(32F or below) and most of the year temps are well below 0 degrees(F). We were wondering if a cob structure would be able to avoid cracking or altogether crumbling in prolonged subarctic extremes and if you by chance could put us in touch with anyone who has built with cob in alaska or similar lattitudes(63 N or higher). Any information or general advice would be greatly appreciated. Thank you
Hi there Aidee,
I think cob might give you a difficult time up there.
Here is a forum that has many cob experts to answer your questions: permies.com/forums/f-76/cob
Cordwood or strawbale might be a better choice.
Check out the Permies site.
Best! Good Luck!
I built a log cabin in the 70’s and helped a friend build a cordwood home in the mid 80’s. Rob Roys Logend Homes book was one we bought back then. Nice to see he is still active. Website looks good. So many really beautiful structures. Gotta do another one before I get too old.
