Traditional Resources, New Materials. Editorial ERA21 #01/2026

Filip Landa

When we began exploring the topic of new materials in contemporary construction, we found an almost endless spectrum of possibilities. Some technologies have already become relatively common—like glued or cross-laminated timber and 3D-printed concrete—while others remain experimental, such as the application of biotechnology in the development of new composites, or materials and structures shaped by living organisms, including mycelium, microphytes, or even higher organisms like the silkworm.

Our magazine has already addressed some of these phenomena in its previous issues. For example, in ERA21 #04/2019, Post-Digital Architecture, we introduced “robotic wood” or the Hiveopolis project, which employed honeybee colonies as active agents in the construction process. Similarly, 3D-printed structures and buildings made of earth and straw have become a recurring feature of the magazine, always in relation to the given theme.

For this issue, we have selected several examples from this wide range of approaches. What connects them, however, is a shared focus on sustainability.

Although many of the presented materials may appear new, they often represent a return to natural resources and processes—a shift away from pure techno-optimism toward more traditional and natural methods. In this sense, they point to a renewed use of the planet’s existing resources in the creation of new materiality. This idea is also reflected in the title of the issue—(Re)Discovered Materials and Innovations.

The space of the magazine is, of course, limited, and our aim is not to cover all material possibilities available today. Instead, consider this issue a guide that may open the door to further exploration and inspiration.
