A pioneering 3D-printed house just popped up in Xian, China - and Chinese company ZhuoDa "built" the two-story villa in less than three hours. Made up of six 3D-printed modules, the house was assembled like LEGO bricks before a live audience who were then invited to explore the interior. The modular fireproof home can withstand a magnitude-9 earthquake and is made from a special construction material the company is keeping secret. The company completed approximately 90 percent of the construction in an off-site factory before shipping the modular pieces to the installation site. This efficient and timesaving process dramatically reduces construction costs to just US$ 400 - US$ 480 per square meter. According to An Yongliang, the developing engineer at Zhuoda, the 3D-printed villa only takes about 10 days to produce from initial construction to final assembly, while it typically takes half a year to build a traditional villa. The house is capable of withstanding high-magnitude earthquakes because the modules, each weighing over 100 kilograms per square meter, bear weight independently. The steel-framed structure home can also be filled with heat-insulating materials. The Zhuoda Group has filed over 22 patents on their technology and is keeping their top-secret material under wraps. However, the company's vice president Tan BuYong has revealed that the new material is sourced from industrial and agricultural waste, is fireproof and waterproof, and is free from harmful substances such as formaldehyde, ammonia, and radon. After the structural framework was 3D-printed, the company applied decorative sheet textures to each module before final assembly. Homeowners will be able to choose from a variety of decorative textures, such as jade, marble, wood, and granite. Herbs can even be embedded into the walls of the house for "built-in aromatherapy". The buildings can withstand wear for at least 150 years. On January 2015 a Chinese company WinSun has successfully 3D printed a five-story apartment building and a 110 square meters villa from special print material. China's newest mansion is not only made from recycled materials, but the sprawling 110 square meters home was made with 3D printing. The luxury mansion was 3D printed in layers, using recycled stone and construction waste.

Blundering Chinese officials were forced to cut a motorway in half to go around a block of flats after they accidentally erected the building in its proposed path then realized it would cost too much to relocate the tenants. In Xi'an, Shaanxi province in western China construction workers had to squeeze the eight-lane highway into four and subsequently left furious residents stuck in the middle of a busy road. They had just been moved from their previous homes to make way for a park so refused to move again unless they were heavily compensated. So the council decided to save a small fortune by leaving the flats in place. The council then started negotiations with the tenants, but with their new, modern flats they wanted even more compensation, and after several months of failed negotiations, the council simply gave up and built around the problem. But the road has been branded a waste of time and money as it has done little to solve the problem of rush-hour congestion that it was designed to solve. It is not the first time a blunder or a dispute has led to bizarre construction projects in China. In December, an ancestral grave was left standing in the middle of a building site because the family of the deceased refuse to let it be moved. The single gravestone was left on top of a ten meter high mound while workers erected a high-end block of flats around it in Taiyuan, capital of northern China's Shanxi Province. The tomb is the ancestral grave of a villager from nearby Longbao whose family is unhappy with the level of relocation compensation that has been offered. Last year, Chinese workers famously had to build a motorway around a single house when the owners refused to relocate. Luo Baogen and his wife insisted on living in the half-demolished building in the city of Wenling, in Zhejiang province, because they believe that the compensation offered by the government to move was not enough. However, the house was finally pulled down after the couple reportedly accepted an increased offer of compensation from US$ 35,3 to 41,8 thousand. Such curious things happen all over the world.
