Architects 3D-Print a House in Luxembourg in Just a Week

The architects presented Tiny House Lux, a 47-square-meter single-story apartment building that was fully 3D printed in a week. The project demonstrates that 3D printing technologies are moving beyond experimental solutions into a full-fledged construction tool. Its purpose is to test the possibility of rapid construction of compact housing in small and complex areas, which traditional methods often find unsuitable. The house is located on a narrow plot 3.5 m wide and 17.7 m long. A structure was printed from a cement mixture with additives suitable for extrusion. The Coral printer formed the building’s box in layers, after which the builders installed the roof, windows, doors and engineering systems within three weeks. The building is supported by screw piles and partially cantilevered above the slope, reducing interference compared to a concrete foundation. The roof is equipped with solar panels, and the walls have retained the characteristic “corrugated” 3D printing structure. The budget was about 320,000 euros, but the architects noted that for Niedernanven it is lower than the average cost of housing and is considered as a step towards expanding affordable housing construction.
