In making this stool, you will be producing an unconventional yet efficient building material with both insulation and thermal mass properties. Made up of hemp hurd, lime, and a binder material, hempcrete (as a single material) is a natural and carbon negative alternative to the abundant layers of insulation, drywall, cladding, etc… that cover the walls of our homes today. In some ways, the simple instructions for this stool are the same as instructions for building a wall of your home with this material. More on hempcrete here. The simple assembly process takes up to 1 hour to complete.

Hollow 80mm T-slotted framing is a natural form for a vessel. The extrusion process creates beautiful and functional grooves on the exterior as well as weight and material saving cavities on the interior. The full assembly process for the 9.5in (24cm) tall vase takes less than 1 hour to complete. Steps include applying a rubber pad and sealer to the bottom and filling the cavities with some epoxy glue. The parts cost less than 100 USD on average. While caring for your anodized (non-black) vase, clean and re-fresh water regularly to prevent oxidization.

It’s actually really fun to make this bowl. You are up against time because the hot plastic hardens as it cools, and while you can always re-heat and make adjustments, the ultimate form will reflect your quick movements to counteract gravity and the increasing tension in the plastic. The finished translucent bowl is roughly 13in (33cm) in diameter and it can be made larger by simply adding more plastic in step one. Assembly can be completed in about 1 hour and the parts cost less than 50 USD on average.
