Shaping the Curve: Crafting Curved Corners in Hemp Walls
In the world of hempcrete construction, where form meets function and sustainability is the goal, it’s often the smallest design details that spark the biggest conversations. One such detail — the elegant curved corners on internal hemp walls — recently drew admiration on the Hemp Building Facebook page, thanks to some eye-catching builds in rural Victoria.

The work comes courtesy of builder Andrejs Liepins, with Viviana Bambino assisting on the job. While Viv modestly downplays her role and says she didn’t snap many photos of the formwork, the result speaks volumes.
So, how were these smooth, curved corners achieved?
The team used custom formwork made from structural ply, carefully routed to accommodate PVC pipes that defined the curve. These were held together using button screws, allowing for quick setup, solid structure, and clean removal after casting. The result: organic, rounded corners that soften the space and elevate the aesthetic without compromising the integrity of the hempcrete.
This method showcases the flexibility and creativity that hempcrete construction allows — from rustic cottages to architecturally refined homes, the material continues to surprise.
Let this serve as a little inspiration for your next build: with the right formwork and a bit of routing magic, hemp walls can be as graceful as they are green.
