Building a house within a house would also add a lot of soundproofing. I wonder if anyone has studied whether people like or dislike not being able to hear what is going on outside the house. Seems like there would be some safety issues, like you can't hear someone outside calling for help and can't hear how intense a storm is or if a car/truck drives up, but on the good side you also can't hear the neighbors lawn mower and wood chipper. Some people may like feeling connected audibly to the outside world and feel more isolated if they can't hear nature while others may like that it makes the outside world go away. It may not be possible to hear wind chimes. An emergency siren may be difficult to hear, though emergency sirens are not used much any more in the USA, except near nuclear power plants and such. Maybe that needs to change with climate change. In fact, changing climate may need to be part of the calculation on how houses are built (not just increased wind resistance but also estimates of how warm/cold the area will be year round in the future.) It would be great if houses could be 3D printed so people are not limited by increased costs due to homebuilders not upgrading their skills. House design may need to change radically on the East Coast (Nor'easters's) and in Tornado Alley and on the South coast (hurricanes).
