Only a short time later, the printing of what is currently the largest apartment building in Europe was executed. The project, for which a total of only six weeks of printing time was estimated, showed that 3D construction printing is also suitable for the construction of large residential units. The 5-family house was built in Wallenhausen, Germany. It has a full basement and offers five apartments on three floors with a total living space of about 380 sqm (4,090 sqft).

The special feature: This is not a research or demonstration project, but the apartments are leased. Only one apartment is used as a show apartment.
