About us
Structerra was born out of the desire to establish an engineering firm that brings different elements together—not just building materials. Structerra stands for order, concept and precision; Terra for nature, intuition and tradition. We are creative yet grounded, precise yet flexible, pragmatic yet visionary. Allow us to introduce Structerra.
Agreement based on quality
Structerra is the result of the vision of two engineers with different backgrounds, complementary skills and a shared conviction that civil engineering is a bridge between two worlds: the world of ideas in designs and models, and their translation into tangible structures.

Dimitrios Piskas
Engineer, lecturer, lifelong learner
After completing his diploma at the University of Thessaloniki (2012) and an MSc as an ETH Zurich scholarship holder (2014), Dimitrios began his career as a civil engineer at Basler & Hofmann AG. Over eleven years there, as a civil engineer, project manager and member of management, he had the opportunity to support prominent construction projects and clients. With further training in philosophy, computer science and higher education pedagogy, and in parallel as a lecturer at ZHAW since 2022—currently as Deputy Head of the Civil Engineering degree programme—Dimitrios enjoys taking on a variety of roles. At the end of 2025, he founded Structerra AG together with Karol.

Karol Trojanowski
Engineer, reviewer, versatile problem solver
With a BSc from the Cracow University of Technology and an MSc from ETH Zurich, Karol began working at engineering firm Heierli AG while still studying. As a project engineer and later project manager, he gained experience on interdisciplinary building construction and infrastructure projects. His additional experience in geology, geotechnics and structural dynamics at Jäckli Geologie AG and Trombik AG, as well as three years of service as a building damage inspector at Baloise AG, complemented his diverse project portfolio, which ranges from expert reports and measurement campaigns to maintenance work at foreign nuclear power plants. At the end of 2025, he founded Structerra together with Dimitrios.
Our values
There are many design offices—but only a few like Structerra. We offer more—something that stands out from what is usual in this industry—and investors appreciate this step beyond the ordinary.
Quality
We stand out through solutions that enable good architecture, reduce risks and streamline work on site.
Creativity
We can handle unusual projects and challenges that demand ingenuity and unconventional thinking.
Holistic approach
Building construction, geotechnics and structural dynamics from a single source means fewer interfaces, misunderstandings and errors. We do not allow ourselves tunnel vision.
Responsibility
We build not only structures, but also partnerships. We personally stand behind every project, and our clients’ goals are our goals, too.
Attentiveness
We listen with focus, ask constructive questions, and are open and willing to learn. We work as equals, believe in collective intelligence, and put the project at the centre.
