the world\'s first family to live in a 3d-printed home
Bedroom property is the prototype of a large project designed to make the building of the House faster and cheaper.
Will this lead to a shift in the construction industry?
By designing curved walls to reduce the impact of humidity and digital control for the disabled, the House could be an expensive implementation of the architect\'s vision.
But it took 54 hours to print.
The contractor still has four months to add things like windows, doors and roofs
The construction cost is around £ 176,000, 20% cheaper than building the same building using a more traditional solution.
The group now believes they can print the same house again within 33 hours. The 95m (1022ft)square house -
Built for a family of five in Nantes with four bedrooms and a large central space
It is the cooperation between the municipal council, the housing association and the University of Nantes.
Franck Trichet, head of the committee in terms of technology and innovation, said that the purpose of the project was to see if such a building could become the mainstream of housing and whether its principles applied to other public buildings, such as stadiums.
He believes that this process will disrupt the construction industry.
\"The paradigm of the construction process has not changed in 2,000 years.
\"We want to sweep away the whole construction process,\" he said . \"
\"That\'s why I said we were the beginning of a story.
We just wrote the past.
Now, he says, their work will \"force\" private companies to \"pick up pens\" and continue the narrative.
The house was built in a poor neighborhood in the north of the town, partly funded by Parliament.
Nordine and Nouria Ramdani and their three children are the lucky ones to be selected to live there.
\"It\'s a great honor to be part of this project,\" Nordine said . \".
\"We live in a block in our 60 s, so it\'s a big change for us.
\"It was really amazing to be able to live in a place with a garden and a separate house.
\"The house was designed by a team of architects and scientists in the studio and then programmed into a 3D printer.
The printer was then taken to the website at home.
It works by layering print up from the floor.
Each wall consists of two layers of insulator polyurethane with a space in the middle
The middle is filled with cement.
This creates a thick, insulated, fulldurable wall.
Windows, doors and roofs are then installed.
Look, you have a home.
The house is the idea of Benoit Furet, who is in charge of the Nantes University project.
He believes that within five years, they will reduce the construction cost of such houses by 25% while complying with construction regulations, and by 40% in 10 to 15 years.
This is partly because the technology has become more sophisticated, the development costs are lower, and partly because of the economies of scale as more houses are built.
Printing also makes architects more creative about the shape of the house they are building, he added.
For example, the house in Nantes is built at 100-year-
There are ancient protected trees on the plot.
The curve also improves the air circulation in the home, reduces the potential humidity and increases the thermal resistance.
The Nantes building is also designed for the disabled, with wheelchair access and everything can be controlled via a smartphone.
And more eco-friendly-
Friendly than traditional buildings, no waste.
Mr Furet\'s dream now is to create a suburban community with the same architectural principles.
He said he is currently printing 18 houses in a project in northern Paris.
He also said he was building a large commercial building with an area of 700 square meters.
\"Social housing is my personal feeling,\" Mr Furet said . \".
\"I was born in a job-class town.
\"I live in a small house. My parents -
Now everyone\'s old-
Still live in the same house.
\"This street is a row of small houses, row by row, all the same.
\"Here I want to create a social housing, but a more modern building.
