Our homes have so many advantages that it is hard to name them all. The biggest advantage is perhaps the energy efficiency. Our homes will never drop below 50 to 55 degrees F in mid-winter with absolutely no heat other than the passive solar and the natural heat from the ground.
We have built custom homes for satisfied customers around the country. Click on the photo above to see photos of a number of our custom homes.
