In 2016, a local builder came to E3 with a vision for his family's new high performance home. The property, tucked back on a quite country road in rural Mt. Juliet, Tennessee, was surrounded by tall old trees and acres of privacy. The builder, Michael, and his wife Marie had picked out a beautiful location for the site of their new family home.

Homeowners Phil and Erica own 200 acres outside of Nashville, Tennessee near Ashland City. The land was inherited by Erica and her siblings from her mother, who had protected it from future sub-division with the Land Trust for Tennessee. Erica wanted to build a sustainable energy efficient home that would honor her mother's legacy and last generations into the future.
