A new public seating area along the Spaarndamseweg in Haarlem, the Netherlands, demonstrates how digital fabrication can upgrade urban infrastructure with less material waste. Dutch company Neolithic created the custom bench together with landscape architect Boudewijn Almekinders and designer Tico Beekman. The team produced the seating element using 3D concrete printing technology.

Reusing Existing Infrastructure

Instead of removing the existing concrete barrier on site, the project team decided to reuse it. First, Neolithic digitally scanned and measured the structure to guarantee a precise connection. The company then developed a custom seating element that fits smoothly onto the existing concrete surface.

As a result, the final design features soft and flowing shapes made from several 3D printed concrete components. Together, these elements form one continuous bench. In addition, the team designed and produced the object entirely through digital processes, which meant traditional formwork was no longer necessary.

Reducing Material Consumption

The project highlights how 3D concrete printing can support circular construction and more sustainable public space design. By preserving the original structure, the project avoided demolition work and reduced construction waste. Consequently, the existing infrastructure gained a completely new function.

Moreover, the team produced the bench on demand and tailored it specifically to the location. This approach helped prevent overproduction and unnecessary use of materials. Unlike conventional concrete casting, 3D concrete printing places material only where it is structurally required. Therefore, the process can significantly reduce material consumption.

At the same time, the finished bench offers durability and requires little maintenance. The design team also developed it for long-term outdoor use. Construction company Dura Vermeer installed the seating element on site.

Digital Fabrication in Public Space Design

The Haarlem project demonstrates how parametric design, robotic manufacturing and digital fabrication can work together in landscape and urban design projects. Rather than replacing existing infrastructure, designers can now adapt and extend what is already available. In this way, digital production technologies create new opportunities for more resource-efficient public spaces.

As cities continue to explore circular construction methods, projects like this illustrate how 3D-printed concrete can contribute to adaptable and low-impact urban interventions.
