DeZeen Magazine has the story, with pictures…
Architect Janjaap Ruijssenaars of Universe Architecture will collaborate with Italian inventor Enrico Dini, who developed the D-Shape printer, to build the house, which has a looping form based on a Möbius strip.
It’s pretty weird looking – sort of like a futuristic hallway more than someplace you would probably want to live. The printer they’re using can churn out sections up to 20 by 30 feet with a mixture of sand and a binding agent, which will be filled with “fibre-reinforced” concrete. They think it will take about a year and a half to build.
