In Nantes, a world first is taking shape: the construction of a house by robot 3D printer. This 95m2 house will include 5 rooms, rounded walls, windows and doors… a set of complex architectural forms, achieved by means of a revolutionary technology, on a site provided by Nantes Métropole Habitat.
This innovative project is led by a consortium of scientists, manufacturers, and public and socio-economic actors. The aim: to quickly build affordable, adaptable, and energy efficient housing.

AN ADVANCED TECHNOLOGY
This innovative system makes it possible to build the walls of a house by 3D printing, on the construction site itself and in just a few days. The advanced technology consists of depositing 3 layers of materials using a polyarticulated industrial robot: two layers of expansive foam serve as formwork for a third layer of concrete. Once the walls have been constructed, the foam is kept in place in order to insulate the house without thermal bridging. At the end of the operation, the mobile robot emerges through an opening provided for the fitting of the joineries.

NANTES, A TESTING GROUND FOR THE CITY OF THE FUTURE
Nantes Métropole’s CityLab is an idea that is both simple and ambitious: the local area is asserting itself as a testing ground for those wishing to develop and test innovative solutions, helping to build the city of the future and facilitate daily living.
This makes it possible to combine the momentum generated by the private and public sectors and citizens within the framework of collective governance, making Nantes an accelerator of innovation, capable of anticipating energy, digital, democratic and demographic changes.

FULL-SCALE TRIALLING
This urban laboratory is aimed at researchers, start-ups, companies wanting to test their life-size inventions in all areas, such as culture, society and art in public spaces.”
