Custom slope stair for Adriaan van Erk

21 Oct 2026 Project All news

For Adriaan van Erk we made a stair for a concrete slope next to a garage. The stair has now been installed and is in use.

Made to fit the slope exactly

No two slopes are the same. That is why we design every stair parametrically, to the exact dimensions and angle of the site. Our robot then prints the stair in special mortars, with material only where it is structurally needed and without reinforcement. That makes custom work as easy as a standard product.

Production in our robot lab.

The result

A safe, durable stair that fits exactly, is quick to install and ready for years of use. We thank Adriaan van Erk for his trust and the pleasant collaboration.

Do you also have a slope that needs to be more accessible? See the project, our slope stairs or get in touch.
