YES! You can build a beautiful, nearly disaster proof home that is so environmentally friendly and energy efficient that the Environmental Protection Agency doesn't have a rating for it. These amazing, affordable homes are not only nearly maintenance free, they will be a long-term investment that you could pass down to your children and grandchildren! Costs to build are comparable to a standard wood-frame home, and they don't require any specialized skills or quirky techniques to construct. What's the secret? These earth sheltered homes use the good earth itself to produce all the benefits you will read about here. How very natural!
