Dutch City Will Become the World's First to Build Inhabitable 3D-Printed Concrete Houses

A new 3D-printed concrete housing development is coming to the Netherlands in 2019, CNN reports. The structures will be the first habitable 3D-printed concrete houses in the world, according to Project Milestone, the organization behind the initiative.

While architects and engineers have been experimenting with 3D-printed buildings for several years, most of those structures have just been prototypes. The Dutch development, located in Eindhoven, is expected to be ready for its first residents by mid-2019.

Project Milestone is a collaboration between the city of Eindhoven, Eindhoven University of Technology, the contractor Van Wijnen, the real estate company Vesteda—which will own and manage the houses—the engineering consultancy Witteveen+Bos, and the construction materials company Weber Beamix.

The five planned homes will be built one by one, giving the architects and engineers time to adjust their process as needed. The development is expected to be completed over the next five years.

The housing development won’t look like your average residential neighborhood: The futuristic houses resemble massive boulders with windows in them. The first house, scheduled for completion in 2019, will be a 1022-square-foot, three-room home. It will be a single-story house, though all the rest of the homes will have multiple stories. The first house will be built using the concrete printer on the Eindhoven University of Technology’s campus, but eventually the researchers hope to move the whole fabrication process on-site.

In the next few years, 3D-printed houses will likely become more commonplace. A 3D-printed home in Tennessee is expected to break ground sometime later in 2018. One nonprofit is currently trying to raise money to build a development of 100 3D-printed houses in El Salvador within the next two years. And there is already a 3D-printed office building open in Dubai.

In Eindhoven, residents appear to be fairly eager for the development to open. Twenty families have already applied to live in the first home.

Notre-Dame's Rooftop Bees Survived the Historic Fire

Following the fire that tore through Notre-Dame in Paris on April 15, fire officials shared that the church's bell towers, stone facade, and many of its precious artifacts had escaped destruction. But the building's centuries-old features weren't the only things threatened by the blaze: The three beehives on the roof of the cathedral were also at risk. Now, CNN reports that the bees of Notre-Dame and their homes have survived the historic fire.

Notre-Dame's beehives are a relatively recent addition to the site: They were placed on the first-floor rooftop over the sacristy and beneath one of the rose windows in 2013. Nicolas Geant, the church's beekeeper, has been in charge of caring for the roughly 180,000 Buckfast bees that make honey used to feed the hungry.

Most people weren't thinking of bees as they watched Notre-Dame burn, but when the fire was put out, Geant immediately searched drone photographs for the hives. While the cathedral's wooden roof and spire were gone, the beehives remained, though there was no way of knowing if the bees had survived without having someone check in person. Geant has since talked to Notre-Dame's spokesperson and learned that bees are flying in and out of the hives, which means that at least some of them are alive.

Because the beehives were kept in a section 100 feet below the main roof where the fire was blazing, they didn't meet the same fate as the church's other wooden structures. The hives were likely polluted with smoke, but this wouldn't have hurt the insects: Bees don't have lungs, so smoke calms them rather than suffocates them.

Notre-Dame's bees may have survived to buzz another day, but some parts of the building weren't so lucky. France has vowed to rebuild it, with over $1 billion donated toward the cause so far.

The Hunchback of Notre-Dame Is the Best-Selling Book in France Right Now

Thanks to current events, Victor Hugo's 188-year-old book The Hunchback of Notre-Dame has ascended the bestseller list in France. The novel follows a hunchback named Quasimodo who is living in the cathedral's bell tower in Paris during the 15th century. Now, following the fire that destroyed parts of Notre-Dame on Monday, April 15, readers in France are rushing to buy a copy, The Guardian reports.

Investigators aren't sure how the Notre-Dame fire started, but they suspect it resulted from an accident rather than arson or terrorism. The blaze consumed the structure's 800-year-old roof and iconic spire but left the stone facade, bell towers, and south rose window intact. France is already planning to rebuild the church, and so far $1 billion has been raised for the cause.

The Notre-Dame cathedral may not have become the beloved landmark it is today if wasn't for Victor Hugo. The Hunchback of Notre-Dame came out at a time when the cathedral was in disrepair, and by writing his book, Hugo hoped to revive interest in the historic piece of architecture. He did just that: In reaction to the novel's success, Notre-Dame underwent a massive restoration that lasted a quarter of a century. Many new elements were added, including that spire that was lost on Monday.

This week, the French people are returning to the book that's tied so deeply to Notre-Dame's reputation. On April 17, different editions of The Hunchback of Notre-Dame occupied the first, third, fifth, seventh, and eighth positions of the bestseller list of Amazon France. A book detailing the history of the Gothic cathedral claimed the sixth slot.
