basement: undergound shelter from nuclear, chemical, biological, asteroid, tsunami, alien, etc attacks with big compartments for a submarine-boat vessel, separate pressurized rooms for various purposes (lab, entertainment room, garage, living room, bathroom, etc)
ground level/first floor: the usual - easy access garage with automated doors and locks, living room, kitchen, bathroom, etc
second floor: bedroom, observatory
the house should be in a form of a dome but with concrete-steel barriers on perimiter to withstand incoming tsunami debri and structurally sound enough to withstand a big earthquake (depending on location, soil conditions, plate tectonics, etc)
roof/outside: PVC, solar, wind, satellite receiver, high gain antenna, etc. ability to stay off the grid in any locale is a plus
Nice plan but inefficient:
Nice outline but only one floor
