Statement

Building with 70 % less material.

Metastruct develops technology for designing and building the next generation of structures: computational design, topology optimisation, proprietary materials and additive manufacturing — for structures that are lighter, stronger and nearly waste-free.

Technology

Less material. More structure.

We combine proprietary computational design methods, topology optimisation, advanced materials and additive manufacturing into a single construction system. The result: structures and façade elements with less embodied carbon, less waste and better properties.

01
Computational design

Parametric and algorithmic models that generate optimal geometry from given loads, constraints and targets.

02
Topology optimisation

Material stays only where it carries load. The structure follows the flow of forces, not convention.

03
Advanced materials

Proprietary mixes and additives for materials with a lower carbon footprint and better mechanical performance.

04
Additive manufacturing

3D printing of façade and structural elements: layer by layer, no formwork, no offcuts.

Process

From load case to finished element.

01
Analysis and targets

We define load cases, geometric constraints and the material and carbon targets of the project. Every element gets clear parameters.

02
Computational optimisation

Algorithms generate and evaluate thousands of variants; topology optimisation removes every bit of material that does not contribute to capacity.

03
Material and mix design

We select or develop the material and additives suited to the geometry and production method — for a smaller carbon footprint and greater durability.

04
Additive manufacturing

The element is printed layer by layer, exactly to the optimised geometry. No formwork, no cutting, no surplus material on site.

Awards

HGK Pitch 2026 · 1st place

Croatia's best sustainable innovation.

At the Croatian Chamber of Economy's “Support Sustainability” conference, Metastruct took first place in the Sustainable Start-up category among six finalists from across the country.

“Our ambition is to become a globally recognised ConTech company that accelerates the transition toward climate-neutral construction — creating high-value intellectual property, skilled jobs and long-term economic value.”

Team

Engineers, architects, researchers.

Metastruct grew out of the meeting point between academic research and construction practice. We build what the lab proved possible and the site proved necessary.
