Meghan Simone and Dave Eiermann pulled out all the stops to ensure that no green-building product was left behind for their new home.Building a 1700-square-foot home in Bartlett, NH, their approach to “green building” is to build “a non-toxic home that will live and breathe a healthy life like the people who will dwell in it,” says Simone.
