Jim & his wife Nancy have launched a campaign on indiegogo to build Underhill, a green-roof house! Currently 50% complete, Underhill will have a full 12" of earth on its roof, supporting a full restoration of the woodland habitat in which the house is set.  The house will conserve energy, reduce stormwater runoff, minimize the urban heat island effect, and maximize habitat for plants & animals.  Visit http://www.indiegogo.com/projects/build-underhill/x/1817452.
