Flax and hemp redefine sustainable construction

The Alliance for European Flax-Linen & Hemp is highlighting a new wave of innovation in architecture and civil engineering that places flax and hemp fibres at the core of sustainable construction. As the global building industry looks for eco-friendly alternatives, these natural fibres are gaining attention for their strength, versatility, and low environmental impact.

A notable example comes from the University of Stuttgart’s ITECH Research Pavilion 2024 in Germany. Two lightweight structures have been built using filament-wound flax fibres, showcasing both strength and design flexibility. The main structure uses 20 roof beams made from Terre de Lin’s flax fibres, processed by HA-CO Carbon GmbH. A second structure features a blend of wood and flax from Safilin. Both designs were created using advanced coreless robotic winding technology and serve as striking examples of sustainable architecture.

In façade and cladding systems, flax is also making its mark. French company Temca has completed 880 shading panels using ampliTex flax fibre from Bcomp for a school building in Marseille. The panels, designed by renowned architects Rudy Ricciotti and Roland Carta, offer a lightweight, durable, and energy-efficient alternative to traditional materials, with fire-resistant and UV-protected finishes.

Dutch company NPSP is also leading in bio-based public infrastructure. Working with Alliance member Procotex and material partner Nabasco, they have contributed to projects such as the eye-catching green façade of Amsterdam’s NEMO Science Museum. These façades combine flexible design possibilities with high fire safety, pointing to a future where bio-based materials define modern urban aesthetics.

In another development, DEMGY and rooftop garden experts PLANTIKA have collaborated to create FLAXCOMP® sandwich panels for green roofs. These flax-based panels replace aluminum bases, improving water drainage and reducing environmental impact. If trials prove successful, this approach could lead to more widespread use of flax in green infrastructure.

“These projects show how the industry is moving toward smarter, sustainable, and high-performance buildings using Europe’s natural fibres,” said Bruno Pech, Innovation Project Manager. The Alliance continues to support and promote these developments, pushing the boundaries of what is possible with flax and hemp in modern construction.
