Michael’s Dome at Sacred Garden Sanctuary


“Sacred Garden Sanctuary is an intentional community dedicated to sustainable farming and lifestyle, on 40 acres of land located near Douglas, Arizona.

We are currently planning to use a modified Cal-Earth (earth bag/tube) construction, after completing a trial dome. We plan to use a more inexpensive tubing material, which is used for onion sacks, rather than Cal-Earth “sandbag” tubing. Adobe domes will be heated in the winter and cooled in the summer mainly using passive solar and thermal mass to moderate day/night temperatures, which can vary up to 50 degrees in a 24hr period. This may be supplemented by wood stoves in the winter and evaporative cooling in the summer, if necessary. Progress on the dome has been slow due to other priorities, but we have done some more coating with the asphalt emulsion layer.

After putting on a partial “finish” coat of plaster, we have decided to rock-and-mortar the exterior instead of plastering. This will have the following advantages:
• Higher longevity
• Reduce maintenance to near-zero
• Add some further structural integrity
• Improved aesthetics”
