That much underground would be awful for mold allergies. And IDK how much time and money is needed to deal with nothing ever getting permits
Very unusual unfinished, unpermitted concrete bermed home with unpermitted septic system and no power on 4.97 secluded, wooded acres. Individual well. 4-1,000 in ground propane tanks, 500 gal water storage tank. Used to be powered by a solar system & a generator, both of which were stolen (and other equipment) but electric nearby. Owner was working on a self-sufficient home but passed during construction having spent over $400K on the project. Current best use may be to bring in power, do engineering calculations & permit this structure as a shop/ag building & build another home/manufactured home. Owners have some construction photos. Great buy at the list price. There is still a lot of value there. Located in the country East of Olympia.
How bad it would be for air quality and exchange would come down to the HVAC almost entirely as long as the build quality is there. A modern energy efficient house is sealed so tight that the sum of all air leaks to the outside is smaller than a baseball.
The build quality would of course be the biggest concern, if they didn’t do the weatherproofing and water management right there would be water seepage and a high likelihood of a roof leak that would be horrendous to address.
