It's design and structure is based on the Cal-Earth prototype model in Hesperia, California, which passed structural tests for California code, leading to its permit in the city of Hesperia, California. It has been developed as an alternative for sustainable living, using self-help techniques. The new invention of offset vaults in the design eliminates corridors and creates a feeling of spacious interior. More vaults or domes can be added later. Start with 1 bedroom and grow to 4 or more.
Wind scoop faces prevailing summer breezes for cooling.
Doubles as winter fireplace. Indoor temperature lag due to thermal mass of material. Standard doors, windows, and interior fittings can be bought at local hardware stores. Can be built by hand using self-help techniques, or by machine using standard concrete pumps. Please contact Cal-Earth for dates.
