For about seven years, Trey Farmer and his wife Adrienne Lee Farmer lived in a circa 1914 Craftsman-style bungalow a few miles west of downtown Austin. With a new baby in their lives, they decided they were ready to turn their drafty home with no subfloor or insulation into something that would be more comfortable and sustainable.
