Carl Gradek’s hempcrete project stands as a major milestone in Austin’s building landscape. As the first permitted structure in the city using hempcrete, it reflects a deep commitment to craftsmanship, innovation, and sustainable design. Built from a blend of hemp hurd, lime binder, and water, hempcrete is a carbon-negative material known for its fire resistance, thermal performance, and breathable, mold-resistant qualities. This home was constructed in collaboration with Micropaz, a Texas-based company that developed and supplied the lime binder mix used throughout the build.
