The building is mostly going to be assembled with wood and recycled paper (insulation) but of course we need a solid base. So after installing a basic sewage system we had the concrete foundation coming in today. Next steps are bringing in a layer of recycled glass (looking like small pumice rocks) to avoid the cold coming up from the ground, placing temporary borders and then having a layer of concrete (with metal fibers) spread out on top of all that. This will be the factory floor. But it'll be 2018 when we see that happening.
