Building underground should get additional attention, given this Spring\'s experiences with tornadoes. In fact, you\'d think there would be a natural synergy between building underground and the manufactured home industry. Install prefab housing underground and suddenly it\'s no longer a death-trap!

teletubbies...

Perfect realization of Liberal dreams. Humans relegated into holes so as not to upset Gaia with our bacteria-like presence.

Please check out sustainable conrete domes and pass around that information. Its not new but its a good thing to avoid damges from earthquakes tornadoes hurricanes floods and nuclear damage.I thnk the building inudustry should stop making paper plastic houses they are not healthy.

Troglodytes forever! I agree with \'Loving It All\' - we should take a page from our pioneers who built of adobe and turf covered dwellings. Imagine the forests, transport costs and materials we\'d save! I\'ve done just about all I can with my recycled 70 year old house, but if I could start over it would be underground! Well done iSigma, Inc.!

This design is fine for heat and tornadoes, but not all areas will accommodate a home underground because of chance of flood.

....when can I move in! (:>)

Maybe this will satisfy the yearnings of atavistic protection and security from the architect, as well happens since Cappadocia and chineses cavern\'s era, passing by Christian Müller, who surely was inspired by its country\'s cheese too.
However, we all know the cost of support of underground structures and the great need of sunlight in all environments for a good home.
The ecological appeal of the project is not enough to justify such type of construction, at least curious and claustrophobic.
Perhaps one day, on account of human overcrowding, we will even have to go back to the origins and make of hills and mountains, a big Swiss cheese.
Will be this the architect\'s choice?

Insecure much?

Love it, but before you call it a \'zero carbon\' house, show the \'carbon footprint\' of the construction process. Going to need a lot of \'carbon spewing\' bulldozers and backhoes.
