The solar-heated garden room stays above freezing in winter and reaches up to 100 degrees Fahrenheit in the summer. It features a winter fish pond (fish and plants return to the outdoor pond in the summer), a green ash tree growing through the roof, a wooden deck floor with earth underneath, and a rock in the floor (symbiotic with the tree).
The home was built, symbolically, around the green ash tree. A rubber membrane around the tree at the ceiling keeps water and air out and allows room for the tree’s growth. The room opens to the outdoor pond and a stone patio by Montgomery's studio
Windows from the Master look out onto the garden room.
