College Student Builds Sustainable Doghouse From Versatile Hempcrete

Posted in Ministry of Hemp

“It’s mold resistant, it’s pest resistant, it’s fire resistant.”

Leigh Humphries, from Wilmington, North Carolina, is passionate about hempcrete, the sustainable building material she used to build a unique doghouse.

Humphries recently graduated with a degree in Sustainability Technologies from Cape Fear Community College, and the doghouse was her “capstone” project in the vocational program.

While you won’t yet find hempcrete doghouses shading Fido from the sun in many back yards, it’s a building material with proven benefits and a growing appeal. Hempcrete homes are popping up from Kentucky to Alaska and beyond.

When we heard about Humphries exciting project through coverage on Wilmington’s WWAY news, we reached out directly to find out more about why she chose hempcrete, what it took to build the doghouse, and how her project was received in her community.

‘A really healthy building’: The many benefits of hempcrete

Cape Fear’s Sustainability Technologies Program has a dual focus on green energy and sustainable building. Humphries told us that while she enjoyed learning about renewable energy technologies, “I kind of immersed myself in the construction and building science part of it.”

She first heard about hempcrete in her Green Building class, which offered a broad overview of various sustainable building options. Captivated by hempcrete’s potential, she immediately began researching ways she could use it in her final project.

“I started collecting some research and talking to people,” Humphries recalled. “Finally it came time for my capstone class and I went for it. I got the approval of my academic advisor and went with the doghouse idea.”

One of the most appealing features of hempcrete for her was its vapor permeability, which allows structures to “breathe.” This helps make hempcrete extremely resistant to mold and other health hazards.

Hempcrete also has no volatile organic compounds, toxic chemicals found in many other, more common building materials.

“It’s a really healthy building to live in,” she observed.
