I have a situation. There is this family who is attempting to move to some property where it is extreme HUMIDITY. If you build out of wood, it either rots or the Bugs eat it, or it MOLDS. SO, what IF you built a, two story round concrete, Cylinder Dome House . I know this is NOT a frontier look, but this is in an area of this country where the Delta water is high half the year and the wind might just Blow your roof off. One issue is the MOLD, so my thinking is to seal the concrete. Can this be done to prevent MOLD ? This structure as futuristic as it might appear has to be large enough for eight people but, keep the cost down. I know that gowing UP is less than gowing out, or is it ?
