Photos + video: Dutch couple acquire Europe’s first fully 3D-printed house

Dutch couple have become the proud new tenants of the country’s first ever 3D-printed house.
Elize Lutz and Harrie Dekkers have been given the digital key to the gray, boulder-shaped building in the Bosrijk neighborhood of Eindhoven, in the southern Netherlands.

The single-story home has more than 1,000 square feet of floor area, with a spacious living room and two bedrooms.

Lutz, 71, and Dekkers, 67, replied to an advertisement seeking tenants for the groundbreaking project.

The house was designed to blend in with the landcape.

Now retired, the former shopkeepers from Amsterdam will move into their new home on August 1 — although their tenancy will last for just six months.

“We are always looking for special places to live,” Dekkers told CNN. “It’s so unusual.”

The house is the first in a series of five from Project Milestone, a joint construction and innovation project from Eindhoven University of Technology, the local municipality, real estate investor Vesteda and three sector specialists: construction company Van Wijnen, building materials maker Saint-Gobain Weber Beamix and engineer Witteveen+Bos.

According to the project’s website, it “is the world’s first commercial housing project based on 3D-concrete printing.”

More than just an experiment, the house was built to be fully habitable for several decades and designed to resemble a boulder in order to blend with its natural surroundings.

It consists of 24 concrete elements, which were printed layer-by-layer at a plant in Eindhoven. The elements were then transported by truck to the building site and placed on a foundation.

The printer consists of a robot with a mechanical arm that can move on a track in seven different directions to lay mortar in a pattern on a printbed — as designed on a computer.

The dry mortar in a silo is mixed with water in a mixer and pumped via a hose to a nozzle mounted on the end of the robot arm.

The entire project took around a year to complete, though the physical printing took just 120 hours. The rest, say the project backers, was down to “trial and error” and perfecting the construction process.
