Proof Is Possible Tour

Grace and Corbett Lunsford's PROOF IS POSSIBLE Tour is a hands-on, entertaining weeklong event in 20 cities across the U.S. to generate private market demand for home performance testing in home improvement and new home construction.

Corbett, Grace, and their new baby went on a 13,000 mile, 34-city U.S. Tour from April 2016-January 2017 in the world's highest performance tiny house on wheels, the #TinyLab.  Their mission was simple: to revolutionize the home market by teaching consumers and contractors alike to use scientific testing to prove the work gets done to quality standards.  Each city on the Proof Is Possible Tour was sponsored by a local company who shares the passion for empowering homeowners and changing the game.  Along the way certain cities shared in filming of the couple's forthcoming TV show Home Diagnosis, screened their award winning Indie film The Other One, and shared music with intimate live performances from the couple's collaboration, Mysteriam. They invited over 7,000 strangers into their home on the tour, and now live in Atlanta, Georgia, but you can see more details and videos below!
