I plan to use concrete walls, ceilings and floors, with radiant heat, supplied by solar energy cells. The walls will be 12" thick, and very safe and efficient. This technique is a little more expensive to build than using lumber, but the energy savings offset the initial outlay for construction in a few years. Plus, we use far less trees, and obtain a better product that will last for generations.
