Couple retires to fully compliant 3D printed concrete house
A retired couple from Amsterdam recently moved into the very first Dutch 3D printed concrete house in Eindhoven, the Netherlands.
The project highlights the successful collaboration between multiple stakeholders from government, knowledge institutions and industry. While the municipality was co-initiator and facilitator of the project, TU / e carried out research and developed models to enable 3D printing of concrete, Saint-Gobain Weber Beamix developed the particular types of concrete mortar required for the 3D printing, Witteveen + Bos worked on the building engineering and structural aspects and the construction company Van Wijnen built the house. The house is now owned by residential real estate investor Vesteda, who rents it out to individuals.
The 3D printed concrete house, which fully complies with all the strict building requirements of the Netherlands, is a 94 square meter single storey detached house with a spacious living room and two bedrooms in the Eindhoven district of Bosrijk. The giant boulder shape of the house blends in well with the natural location and demonstrates the freedom of form facilitated by 3D printing concrete.
The house consists of 24 printed concrete elements, printed layer by layer in the printing house in Eindhoven in around 120 hours. These elements were transported by truck to the site and placed on a foundation and provided with a roof and frames, followed by finishing.
Thanks to the R&D which made it possible to print concrete in all kinds of shapes, the project team was able to design the house in the form of an irregular rock. While printing the sloped walls was a major challenge, the team were able to master the process, helping to open the door to a completely different type of construction than the usual rectangular house designs.
