Mr Hemp House™ exists to make non-toxic, healthy homes accessible to every American family. We assess, educate, and build — using the safest materials available.
Founder & CEO · U.S. Military Veteran
Christopher Penn founded Mr Hemp House after discovering the profound health impact that building materials have on the people living inside them. After years of researching indoor air quality, toxic off-gassing, and bio-based construction alternatives, he developed GaiaCrete® — a proprietary hempcrete alternative engineered to be permanently mold-proof, fire-resistant, and completely non-toxic.
As a military veteran, Christopher brings discipline, integrity, and a mission-driven approach to everything Mr Hemp House does. His goal is straightforward: replace the toxic materials in American homes with solutions that protect families rather than harm them.
Today, Christopher leads a growing team of certified installers, educators, and healthy home advocates. Through Mr Hemp House University (MHHU), he trains the next generation of non-toxic building professionals. Through the Healthy Home Assessment program, he helps families identify and eliminate hidden toxins in their homes.
Every recommendation we make prioritizes the health of the people living in the home. No exceptions.
We operate with the discipline, transparency, and accountability that military service instills.
GaiaCrete® is carbon-negative. We believe healthy homes and a healthy planet go hand in hand.
We publish research, guides, and tools so homeowners can make informed decisions — whether they hire us or not.
