One: Using Natural and Recycled Building Materials
“To build the Nave Tierra, we used recycled and natural materials as much as possible” Alejandro begins. “Old car tires form the basis of the walls. Filled with earth and clay, they are extremely strong building blocks for load-bearing walls. The walls are so wide that they do not need a concrete foundation. That saves cement and therefore a lot of CO2, which would otherwise have been released for its production. We also recycle glass bottles and aluminium cans to reinforce the walls, which are finished with clay and natural dyes. Finally, the wood that we use for the window frames, doors and the roof construction has removed CO2 from the atmosphere in order to grow.”
