Large 3D printer building clay dome structures for the TECLA house using local soil in Italy.

Italian architects 3D-print a house from local clay— without using traditional bricks — by sourcing soil from the site itself. The question is no longer if it works but how much it can cut costs?

Cranes lifting prefabricated apartment modules into place during construction of a modular building in China.

A crew of around 100 workers and two cranes turned what looked like oversized shipping containers into a 26-story tower in five days. The real takeaway is that the slowest parts of construction – wiring, ductwork, and finishes – were done before anything arrived on site
