Lightweight Design is a mindset. We use it to develop integral structural solutions for all building structures.

Our core competencies at a glance

Consulting, planning and project management: str.ucture offers you solution-oriented service packages ensuring competent and efficient support in the implementation of your lightweight design project. 

Make use of our know-how in all fields of classic lightweight design. Benefit from our proven expertise in the construction of membrane structures, in the design of highly efficient building structures as well as in the development and application of innovative materials for lightweight structures.  

• Structural design (Lightweight, buildings and special structures)
• Digital and parametric design from form finding to production data 
• Wind engineering


Implementation – individual solutions for challenging construction projects.

Even concerning its proposed aim for sustainable construction, lightweight design demonstrates its enormous potential. From long-span roof structures and parasol constructions to steady-state and mobile supporting structures through to structural components optimised both for structure and material – str.ucture is designing, planning and implementing lightweight projects worldwide and in many different facets.


Heading for success – str.ucture seeks international comparison.


Pioneering – Innovative Simulation Systems, structural elements and materials for lightweight design.

Innovations are decisive reasons for success. The active involvement of str.ucture in current research projects is therefore of key importance. We pass our advance in knowledge directly on to our clients by means of concrete performance benefits.
