Architects in Amsterdam have started building what they say as Europe’s first full-scale 3D-printed house. They claim it’s a waste-free, ecofriendly wayto design our cities in the future. Forget bricks, tilesand wooden beams. If you want to build a house infuture, it may only requires the fresh plant oil ordiscarded plastic bags and a rather large 3D-printer. We've come to see what appears to bethe ultimate do-it-yourself project. Inside a small courtyard in north Amsterdam lie the first skeletal structures--a black plastic facade and a few steps. These are the first tangible pieces according to the blueprint. Eventually, they will create a five-story canal house. So we are now inside the Kamer Maker which translates as room builder. It’s built inside a huge shippingcontainer. And this also means when they want to transport the technology to cities likeLagos or Mumbai, they can simply move it around and then use locally sourced material for thebuilding products. And here we have at the latest part of the Amsterdam 3D house. This will bethe roof balcony. And the architects say that this is the most sustainable technology forbuilding the homes of the future.

Over half of the world population is really now living in cities and still and sometimes in fairlypoor conditions.

Back in the courtyard, a 3D-printed couch is designed to invite visiters to engage with theconcept. Sitting down on the rather comfortable, if slightly unconventional couch, it demonstrates that traditional furniture can come from the most modern technology. The architects hope it will help people to recognize the ecofriendly possibilities and inspire the next generation to imagine alternative methods of construction.

Soon everything could be 3D-printed.

It might even start creating metal 3D-printers. People could use it to make furnitures.

Therefore, (they) allow us to live without chopping down trees.
