During earthquake liquefaction, when the shaking ground gains liquid-
like properties, this building, which is mostly underground, is designed
to be buoyant. Since it is already positioned for liquefaction, it will
neither float upwards, sink downwards, or topple over. An added
benefit of being
mostly underground is a drop in heating and cooling
expenses by taking advantage of underground temperatures which is
cool in the summer and warm in the winter. Light wells are provided
for comfort.

Specifics about construction? What makes something bouyant in dirt? |

A building floating 20 stories deep in a swimming pool. Windows look out on colorful fish and tasteful undersea plant life, lit by sunlight from above. Swimming and scuba diving are popular as well. |

All you need is the right density to be buoyant. The same
principle as that which applies to ships. |

This just isn't much of an idea. Any building that does not project much above the ground and is robust enough to survive the vibrations of an earthquake is little likely to be otherwise threatened by an earthquake. A solution looking for a problem. |

I think there is a concept called 'Alfa Cube's' : |
|
| |
large dimension, say 1 by 1 by 1 kilometer concrete
construction cubes, just sitting on the land, or even
floating in the sea,... 350 meters submersed, 650
meters of the greatest view !. |

| |
Phoenix caissons. Buoyant in seawater, and liquified ground is much denser. |
|
| |
All you need to do is stop them toppling. |
