China leads the way (maybe) in low cost 3d printed houses

This story is interesting and somewhat strange. Over at they published an article about 10 3d printed houses that were made in one day in China.
Since it was published on April 1st some people thought it was a joke. There are photographs but third-party references are missing.
It is still feasible that it is real story since China leads the way in many technologies (in they own way) ...

From the source article:

A group of 3D printed houses, 200 m2 each, recently appears in Shanghai, China. These building were created entirely out of concrete using a gigantic 3D printer, and each costs only 30,000 RMB ($4,800).

The company behind these 3D printed building, Shanghai WinSun Decoration Design Engineering Co, said it has for years been working on developing the system and its materials. The company owns 77 national patents of construction materials, such as glass fiber reinforced gypsum and special glass fiber reinforced cement.

While Hobbyist models of 3D printers are currently available for only a few hundred dollars and lets users feed plastics and polymers into a machine, the company takes this technology to a bigger level. Using concrete, instead of plastic, WinSun wants to revolutionize the way homes and other structures are built.
WinSun's 150(L) x 10(W) x 6.6(H) m gigantic 3D printer is capable of printing entire building within hours. The 'ink' it used is based on high-grade cement and glass fiber. Like traditional 3D printers, the system carefully spills out those materials layer by layer, consistently building upwar
In addition, it is very impressive that the printing material is recycled construction waste, industrial waste and tailings.
WinSun plans to build 100 recycling factories in the country, one in every 300km, to collect and transform the waste into materials for 3D printing through special handling, processing and separation technology. "There will not be any waste from the construction of new buildings." said WinSun CEO Ma YiHe. WinSun expects 3D printing will save construction companies up to 50% on the cost.
