We believe homes can nurture the people in them and respect the environment around them. So in 1978, Semmes & Co. Builders set out to save the world one house at a time. We built our reputation as a green builder on sustainable straw bale, rammed earth, passive solar and off-grid homes. Then we pioneered more ways to build that reflect creative style, save resources, and cost less to operate and maintain. Today, we invite you to live your values in a beautiful custom-built Semmes home that makes a statement and a difference.
