Just outside Ravenna, architect Mario Cucinella trialed his first 3D-printed earth house this summer. With warm, terracotta tones and a domed, organic form, it looks like something ancient desert populations could have constructed centuries ago. In fact, the primeval appearance belies the state-of-the-art building technology used to create a structure that Cucinella hopes will combat homelessness and displaced communities after emergencies or natural disasters.

Cucinella has dubbed his house TECLA, referring to the interaction between technology and clay. In collaboration with WASP, an Italian company specializing in large-scale 3D printing, Mario Cucinella Architects envisioned a quick build house constructed from raw earth. “I thought this idea of combining advanced technology and using a material that is part of the history of architecture and humanity was a great combination,” Cucinella says. By using natural local materials, he also ensured the builds are eco-friendly and biodegradable. “The goal was to match the agenda of 2030 in Europe of zero emissions.”

This summer, multiple on-site printers busied away constructing the 60-square meter prototype. The 3D printers built up the domed structure in layers, without any need for scaffolding. After 200 hours, the house was complete. It consists of two round, bulbous forms merged together, with rippling exterior walls. 

Inside consists of a living area, bedroom and bathroom. Emerging from the curved walls are fitted furnishings like seating and tables created during the printing process. In the living area, there is a large round skylight, while gently undulating walls lead to the sleeping quarters and bathroom. 

For Cucinella, there are two key elements to his design; that it can be constructed swiftly and that it can be inhabited almost immediately. This is because he has envisaged the raw earth dwellings as emergency accommodation in conditions where housing needs to be provided in a short time.
