The $50 & Up Underground House Book teaches how to build the lowest cost, most sunshine-filled, best ventilated and driest underground houses of all. It teaches how to incorporate greenhouses, root cellars and fallout shelters into an underground home. It covers both hillside and flat land design, and explains how to solve drainage problems with dependable gravity rather then expensive, failure-prone building materials. It also details ways to pass or otherwise deal with the building codes.
