This exciting new line of prefab houses comes to us from Bensonwood Homes, based out of Walpole, New Hampshire. Their Unity House, a Unity2 model built for the president of Unity College, has achieved a LEED platinum rating, making it one of a select group of homes around the country to reach such a lofty goal.
