Building The Future With Harry Hemp

Building a Greener Tomorrow One Hemp Home At A Time

Harry Hemp is a visionary builder and educator championing hempcrete as the future of sustainable housing. His work blends environmental advocacy, technical innovation, and grassroots storytelling.

In an era of climate anxiety and housing crises, one man is quietly revolutionizing the way we think about shelter. Harry Hemp is on a mission is to replace toxic building materials with hempcrete, a bio-composite made from the inner core of the hemp plant and a lime-based binder. His platform, Hemp Homes by Harry, is more than a construction company. It’s a movement.

"Hemp will save the world, if we let it”, reads the tagline on his website. And Harry isn’t just talking the talk, he’s building the walls, insulating the roofs, and educating the public on why hempcrete matters.

The Magic of Hempcrete

Hempcrete is not just a buzzword, it’s a game-changer. Unlike traditional insulation and concrete, hempcrete is carbon-negative (meaning it absorbs more CO₂ than it emits during production). It’s also fire-resistant, mold-proof, and thermally efficient, with an R-value of 2–3 per inch. That means homes stay cooler in summer and warmer in winter, all while regulating humidity and reducing energy bills.

Harry’s website breaks it down simply: hempcrete’s monolithic build and high alkaline mixture create a durable, anti-fungal environment. It’s not just good for the planet, it’s good for your health.

From Builder to Educator

Harry’s journey began with a single hemp build, but his passion quickly evolved into a full-fledged educational platform. His blog dives deep into topics like Hemp Wool vs. Hempcrete, Clay and Lime Plaster vs. Latex Paint, and the rise of Hemp-Wood, a sustainable alternative to traditional lumber. Each post is written with clarity and conviction, aimed at homeowners, builders, and Eco-curious readers alike.

He’s not afraid to challenge the status quo. In one article, he critiques the widespread use of latex paint, advocating instead for natural finishes that promote indoor air quality. In another, he explores the benefits of hemp wool insulation, noting its growing popularity in green construction.

The Road Ahead

Harry Hemp’s vision is bold: a world where hempcrete homes are the norm, not the exception. As climate regulations tighten and consumers demand greener options, Harry’s work is poised to scale. Whether through workshops, partnerships, or viral blog posts, he’s laying the foundation, literally and figuratively, for a more sustainable future. As Harry would tell you: It’s not just about building homes. It’s about building a movement.

I got involved in the Hemp Movement in 1989 when I was hired by Jack Herer to run hiss office. I launched the cable television series ‘TIME 4 HEMP’ on January 5, 1991. Time 4 Hemp is the first TV series in the history of broadcasting to focus strictly on the topic of cannabis. This has given me the dubious honor of being ‘The Father Of Marijuana Television’.
