If this is the future of architecture, the future should be here in, oh, about 18 months. That’s how long the world’s first 3D printed building — Janjaap Ruijssenaars’ Landscape House where floors climb, flip and loop to become ceilings in a mobius strip — is estimated to be completed. The gigantic D-Shape printer will be used to print the building’s hollow shells with a marble-like material, while concrete and fiberglass will be used to reinforce the structure. The cost? US$5-$6 million. The future isn’t cheap.
