While I am certainly no expert on the subject of building with cordwood, it is something that caught my attention some years ago. I believe I saw an article on the subject in Mother Earth.

I find the thought of cordwood construction very attractive. Mainly because most anyone can do it, not too mention it can be done relatively cheaply and at least where I live there seems to be a limitless supply of wood to work with. Assuming your willing to put forth the effort to aquire it.
From what I’ve read cordwood construction goes back around 1,000 years, or so.
As with anything there are pros and cons to cordwood construction. Below are some and there may well be others I’m unaware of.
Pros of Cordwood.
. You can use small pieces
.Added thermal mass
.Decent insulative properties
.Carbon sequestration
Cons of Cordwood:
.Movement of wood can cause cracks or crumbling
.End grain of wood exposed
.Labor intensive
.Expensive if you hire it done
.Lots of wood to morter interfaces
If your considering trying your hand at or just looking into building with cordwood there are books and videos to help you along. Sadly at this point in time, this is just an interest I have and I’m highly unqualified to take a deep dive into it on here. Though I have hopes of changing that sometime this Spring or Summer. I think I may revamp my oversized dog house and see how that goes.
Below is a link that may answer at least some of your questions. And of course if you have insight or experience in the matter, please feel free to comment.
