North America’s first three-storey 3D-printed house completed

Construction of the 420 sq m building near Toronto involved the use of a 3D printer from Cobod International.

The house stands at 3.5 storeys, measuring 12.5 metres from footing to the top of the roof. Three full storeys were printed in concrete using local materials.

The basement of the building was also printed in concrete, with the 3D printer placed directly within the excavation for the home’s foundation, rather than pouring concrete.

The building, which will house four apartments, has been faced in traditional brick and has a steel-framed roof.

Co-founder of nidus3D, Hugh Roberts, said, “nidus3D is proud to be the first in North America to successfully construct a three-storey structure including the below-grade basement in 3D printed concrete. This project demonstrates what can be accomplished by combining nidus3D’s industry-leading expertise and engineering with world-class 3D Printing technology”.

Philip Lund-Nielsen, Cobod co-founder and head of Americas, added, “We are very proud to see nidus3D beat their record by 3D printing the first 3-storey building in our hemisphere – a feat that other Cobod customers outside North America have also achieved previously. Completing the world’s first 3D printed basement is another impressive achievement that only amplifies the technology’s potential to transform construction.”
