Where a old barn once stood at the Phoenix Farm, a new home tucks into the hillside looking up towards the southern prairie. The low, opposing cantilevered roof lines appear like wings ready for flight. This home is the ultimate in sustainability from the ground up. Thermomass foundations, highly insulative walls with rockwool insulation, triple pane windows, recycled metal roof, geothermal heating and a solar field are just some of the environmentally conscious choices made for the construction of this home.
