Zero-waste structures are a much-needed initiative in many parts of the world. Seeking to address this, Mario Cucinella Architects and WASP have come up with TECLA; a completely 3D-printed global habitat made of clay. Clay has been used for centuries in many ancient cultures around the world. It is a cost-effective and environmentally friendly alternative to cement. In fact, cement is solely responsible for 8% of global greenhouse gas emissions. TECLA will be constructed entirely using 3D-printing and locally sourced recyclable materials. Built to adapt to multiple environments, the houses were designed for self-production and looks to be a model for circular housing.
