I like the idea of your house being built into a hill -- of some sort. But won't it get wet and moldy smelling during rainy season? Or don't you have a rainy season in kansas? ~ greedyreader
We do have a rainy season in Kansas, it's called spring, and things like to flood.
There are different measures that we will need to take to ensure that are walls do not end up like this. Different types of liners to keep ground moisture out, and good ventilation. The dry heat source will help dry out the air. As well as paint.
