This Triple Dome Survival Shelter provides much more space than my first earthbag survival shelter. This 915 sq. ft. shelter is for long term survival for a family. It is earthquake and fire resistant, bullet and nuclear fallout resistant. This earth sheltered design is built above grade to reduce risk of flooding. Features include buried cistern between the domes, plenty of storage space, vaulted entry with bullet resistant cellar door. Let’s hope for the best, but it’s also prudent to be prepared for the worst.
