3D house printing has been experimented with for around ten years. Several developers have recently embarked on larger-scale projects in California, Texas and even in Arizona.
The walls of the future houses are built with a very specific concrete, deposited layer after layer using a print head, itself directly controlled by a computer. One of the most spectacular subdivisions is that of Wolf Ranch, in the city of Austin (Texas), which includes nearly 100 housing units, some of which have already found buyers. On average, the purchase price is around $500,000.
