Halcyon Times Dome Home — 8 Comments

  1. From the picture I’d have to assume that you can get some cold temps and this helped influence you using lava rock for the insulation effect?

    How wide are your bags? Did the lava rock (scoria?) hold up well and make a stable wall? Did you have to using any buttressing or wood framing in the walls?

    • Hi David, We used 2,000 18″ x 30″ sandbags and 90 cubic yards of 3/4″ lava rock. We didn’t use buttresses because the smaller domes were buttressed against the main dome, and there was more than 5 square feet between the front windows. We used lintels above the window frames and doorways, but that’s about all the wood we used. The walls are very stable.

  2. Hey Owen,

    Please follow our blogs next week at if you are interested in our next project phase of building earthbag structures in Jacmel, Haiti. We’ll be there from 7th-14th of March and we’ll be sending updates from the jobsite each day on the progress.



  3. Nice! I’ve added them to my blogroll. Which reminds me – have you considered adding a blogroll and list of other site links here? That would be really helpful, if you have the time.
