Eco Homes from the Earth: Cordwood

Categories: Uncategorised

Wouldn’t it be nice to own your own green dream home, made with recycled and natural materials and packed with custom features? Whether you’re an experienced builder or have never picked up a power tool in your life, you can build a natural eco-friendly home with user-friendly, low-cost materials like cob, cordwood, straw and the dirt and wood from your own land. These natural building techniques produce beautiful homes with a small ecological footprint and tons of personality.

From far away, it looks like stone masonry – but get up close and you’ll see that cordwood buildings are actually made from wood stacked firewood-style, and mortar. Debarked logs ranging from 12 to 36 inches can be arranged into walls either in load-bearing round structures or in combination with post-and-beam framing.

Soft woods like cedar and pine are used because they are more stable, with less expansion and contraction. These walls offer both insulation and thermal mass. As with any natural building technique, it’s labor-intensive, but easy enough that practically anyone can do it.

While the mortar typically used for cordwood construction is made from Portland cement, lime and water, some people are beginning to combine cordwood building with cob in place of mortar, as in the owner-built cordwood home above.
