On Friday, July 11, Austinites will gather to celebrate a historic step toward sustainable construction with a special event marking the city’s adoption of hemp-lime—commonly known as “hempcrete”—into the local building code. The celebration, hosted at the Center for Maximum Potential Building Systems (CMPBS) from 6:30–8:30 p.m., will also launch a landmark new book, Hempsteads: Architectural Details for Hemp-Lime Construction by hemp building pioneer Timothy Callahan of Asheville, NC.

The city of Austin, TX on April 10  officially adopted hempline (hempcrete) in the city’s Building Technical Codes as an innovative building material to be used in local construction.
