Residential apartment house in 3D concrete printing

The first apartment building in Europe to be built using 3D concrete printing is located in Wallenhausen near Ulm. It took just six weeks to print the walls and about eight months to complete the building after construction started. Residents will move in in June 2021. The two-story house with a converted attic offers 380 square meters of space for five families.

The innovative manufacturing process has the potential to revolutionize construction. With the help of the BOD2 gantry printer from the Danish company Cobod, PERI GmbH from Weissenhorn can grow the walls in no time: in just five minutes, a square meter of double-skin wall is created in this way. The print head applies the building material layer by layer exactly according to the construction plan designed on the computer including all recesses for sockets or cables for example - re-measuring is unnecessary. Another advantage is that the special concrete is so stable that installation work can already begin in the wall parallel to the printing process.

The walls are printed directly onto the floor slab, in this case a basement ceiling. To avoid thermal bridges, the Schöck Isokorb® T type O provides thermal separation while the Schöck Tronsole® ensures impact sound insulation in the staircase, which is particularly important in a multi-dwelling house.
