The fact that there continue to be advances in the areas of green building should come as no surprise. What is fascinating to watch, however, are the ways in which those developments occur. It requires a great deal of thinking outside of the box and the consideration of a wide variety of complicated factors to ensure that a project isn’t simply greenwashing (i.e., painting as environmentally friendly something which has below surface negative impacts) in an attempt to pander to the currently fashionable green trend. The Australian bio-technology company Mirreco has dedicated itself to just that as part of its mission to help avoid the consequences of global warming.
Their trick in this game has come from the marriage of hemp and 3D printing. Hemp is a product that has garnered a lot of attention both for its potential and for its association, and confusion with marijuana. Hemp has been in use to greater and lesser degrees since it was first spun into usable fiber over 10,000 years ago. Since then, its uses have continued to multiply as it continues to prove to be an incredibly versatile material, including for 3D printing. Mirreco’s contribution to this long history has been to develop carbon-neutral hemp panels that can be 3D printed into floors, walls, and roofs.
The company recently released the concept for a sustainable hemp home, designed by Perth-based architectural firm Arcforms.
“The floors, walls and roof will all be made using hemp biomass, and the windows will incorporate cutting-edge technology that allows light to pass through glass where it is converted into electricity,” Mirreco says.

“In design, for instance, we can create shapes that normally can hardly be made, and that if they can be made, are only produced in large quantities. But here we can do unique industrial custom-made work.”
The construction is created using a plus sized printer that lays down the material in layers, building up into any form, restricted only by structure and imagination. The homes themselves look like the result of a love match between Hobbiton and the Easter Island heads. The ultimate test will be in their livability. It’s all well and good to be able to produce something, but to be able to create it such that the people who inhabit the spaces do so comfortably and with enjoyment is a test that technology often fails. There’s more to architecture than just keeping the rain out, but if anybody is set to take that on, it’s the Dutch, the very birthplace of the idea of gezellig – the act of being cozy and convivial. Consortium spokesperson Rudy van Gurp understands this as well as anyone:
“It’s important to think like the end-user. An end-user wants a nice house in a nice location. Now we’re able to use that technology to create a beautiful house, a place you want to live in and come home to.”
