Our latest Dezeen x MINI Living video investigates a 3D-printed house, which was built in a week, onsite in a Milan square, using recycled concrete.
Engineering firm Arup and architecture studio CLS Architetti collaborated on the project, which was exhibited during Milan design week this year.
The structure was printed by a compact and mobile robot that can print one wall in just 60-90 minutes
The walls were printed with a special mix of recycled concrete, using debris from demolition sites, which cures in five minutes. The mix was developed by one of the world's largest suppliers of cement Italcementi and can be recycled after a building has been demolished.
CLS Architetti told Dezeen that the project aimed to demonstrate that with 3D-printing technology housing can be built quickly and cheaply. The cost of 3D-printing houses is lower than traditional construction methods as the process is more efficient
The house exhibited during Milan design week was only a prototype, however, CLS Architetti aims to improve on the building method to make it sustainable for building long term housing.

A variety of building projects using 3D-printed technology have been unveiled this year. Eindhoven-based Houben & Van Mierlo Architecten are currently building what they claim is the world's first 3D-printed house to be made commercially available to rent, while Dutch robotics company MX3D exhibited a 3D-printed steel bridge during Dutch Design Week this year.
