It is a pleasure to express my opinion about a Dominion Developement house. Simply, because the facts speak loud and clear about what you will experience and enjoy while living in a Earth Craft house. The house is extremely well built and energy efficient. Our monthly energy bills for the past three years average $180. This includes all heat and electricity costs for a 4700 square foot house. The energy cost savings is a wonderful asset and we are confident our purchase was a good sound decision.
