Further development of technology
The realisation of the first 3D printed house was followed by a lot of background hard work on further development of the printing technology. In recent years, Saint-Gobain Weber Beamix, with a branch at the Hurk business park in Eindhoven, has invested heavily in the development of the overall process in order to achieve a unique industrial and scalable 3D concrete printing process. Partly in cooperation with Eindhoven University of Technology (TU/e), this process has been developed and optimised in detail in recent years, resulting in continuous delivery of guaranteed quality. This requires less material compared to existing construction methods, thus saving on CO2.

New designs
Two new types of house have been developed that, unlike the first house, consist of several floors. The new houses derive their structural properties entirely from the printed concrete, a globally unique property within 3D printed housing construction. With their organic design – a habitable 'boulder' – the new houses are perfectly suited to their woodland settings. Two of each type of house will be located in Bosuil in Eindhoven.

Working together with innovation
Characteristic of the Milestone project is the cooperation between government, knowledge institutions and the business community. The municipality of Eindhoven is a co-initiator, driver of innovation and facilitator of the project, the TU/e conducted research and developed models to make 3D concrete printing possible, Saint-Gobain Weber Beamix developed the process needed to deliver consistent quality on the production line, Houben / Van Mierlo Architecten designed the houses, Witteveen+Bos is working on the structural and engineering aspects and the construction company Van Wijnen is leading the project and building the houses.
