Most 3D-printed houses we cover are either arranged on one floor or have an upper floor added later using a timber shell. However, this recent example, by Contec Australia, was entirely 3D-printed across both floors in just 18 hours.

The project is located in Tapping, Perth, and is the only 3D-printed house we’ve seen where both floors are actually printed, except for the experimental Kamp C project. This means that the build process is streamlined and sped up, compared to having to install an extra timber shell, like Icon’s Mueller homes.
