A family in Nantes in France will be the first family in the world to live in a 3D printed house. The house is a dream of Benoit Furet an architect by profession. “Social housing is something that touches me personally,” Mr Furet says. The 3D printed House in Nantes is four bedrooms house and it is a prototype of what is to come in the shape of housing units and large commercial buildings.
The success of this 3D printed house is good news to the building industry. 3D printed houses are easier to build and cheaper and it mean a paradigm shift in the built environment.
The house has been built in a deprived neighborhood in the north of the town and was partly funded by the council. Nordine and Nouria Ramdani, along with their three children, were the lucky ones chosen to live there.
“It’s a big honor to be a part of this project,” says Nordine. “We lived in a block of council flats from the 60s, so it’s a big change for us.”It’s really something amazing to be able to live in a place where there is a garden, and to have a detached house.”
A Building For Special People
The building in Nantes was also designed for disabled people, with wheelchair access and the ability for everything to be controlled from a smartphone.
It is also more environmentally-friendly than traditional construction, as there is no waste.The curve walls also improves the home’s air circulation, reducing potential humidity and improving thermal resistance.
The house was the brainchild of Benoit Furet, who heads up the project at University of Nantes. He thinks that in five years they will reduce the cost of the construction of such houses by 25% while adhering to building regulations, and by 40% in 10 to 15 years. This is partly because of the technology becoming more refined and cheaper to develop and partly because of economies of scale as more houses are built.
Printing, he adds, also allows architects to be far more creative with the shapes of the houses they are building.
How It Was Made
The house is designed in a studio by a team of architects and scientists, then programmed into a 3D printer. Every wall and partition was printed in the site. The printer is then brought to the site of the home.
It works by printing in layers from the floor upwards. Each wall consists of two layers of the insulator polyurethane, with a space in between which is filled with cement. This creates a thick, insulated, fully durable wall. The windows, doors, and roof are then fitted. And, voila, you have a lovely home.
The whole Printed process took 54 hours, doors,windows, and roof were not printed but fitted.
3D Printed House May Mark a New Beginning
The success of this project may most likely bring a shift to the building industry. Mr Furet’s dream is now to create a suburban neighborhood with the same building principles. He says he is currently working on a project in the north of Paris to print 18 houses. He is also working on a large commercial building which will measure 700 metres square, he adds. The house was easier, faster and cheaper to build. The house was 20% cheaper than a how of similar size build with commonly used house material.
The Ramdanis are the first to Live in a 3D printed house and they will not be the last. The house is four rooms and will accommodate their future family expansion. Click here to view a BBC Made video on the house.
