From Angela, a reader in Alaska: “I just wanted to add some updated info. I have been searching high and low for scoria. Alaska doesn’t have readily available sources. I have contacted a long list of people and while we can find the volcanoes and a scoria pit even, there’s no way to get it to the general public.

We’ve covered earthbag houses made with lava rock/scoria in great detail. (Use the search engine on the right if you’re a new reader.) For fun, let’s take a look at a few stone houses made of mortared lava rock. The construction process is obviously completely different, but both enjoy the benefits of lightweight, insulating, fireproof and bug proof volcanic rock.

If you’ve been reading our blogs and websites, you’ll often see reference to scoria. Scoria, also known as lava rock, has numerous properties which make it a great building material. The key breakthrough for earthbag building was Kelly Hart’s house made with bags of scoria. His house stays comfortable year round in a very cold … Read more
