The Provincial Centre for Sustainability and Innovation in Construction (better known as Kamp C) in the Belgian municipality of Westerlo has completed work on a two-story model home, measuring just shy of 970 square feet, that was produced as a single piece by a fixed 3D printer—a world’s first. The concrete printer in question is also Europe’s largest.

Per a press release distributed by the Province of Antwerp, the concrete demo abode is roughly the same size as other single-family terrace residences in the region and roughly three times sturdier than typical brick construction. The entire printing process, which was spread out over the span of three weeks but could potentially be accomplished in two days as the technology progresses, offered savings of up to sixty percent in the realm of materials, time, and budget.

“What makes this house so unique, is that we printed it with a fixed 3D concrete printer,” said Emiel Ascione, project manager at Kamp C. “Other houses that were printed around the world only have one floor. In many cases, the components were printed in a factory and were assembled on-site. We, however, printed the entire building envelope in one piece on-site.”
