Two long-experienced natural building experts are bringing the Carolinas—North and South—together to revive the region’s hempcrete building scene. April Magill, of Root Down Designs, an architect from Charleston, SC has partnered with North Carolina’s Tim Callahan, a legendary hemp-building pioneer who designed and constructed 10 hemp structures around Asheville, NC between 2009-2016.

Idaho-based Hempitecture, Inc., manufacturer of US-grown hemp insulation batting HempWool, plans to open a second manufacturing facility in New York state and roll out several new products, founders say.
