Straw Goes Big: 40,600 m² of Bio-Based Façade for a Dutch Logistics Hub

Lars Keller (EcoCocon Denmark)
In Lelystad, a new logistics center designed by Henning Larsen sets a bold precedent for circular and low-carbon architecture. Its façade—crafted from prefabricated EcoCocon straw panels—merges natural materials with large-scale industrial design. As one of Europe’s largest buildings to feature a straw-based exterior, the project demonstrates how bio-based construction can meet the demands of modern logistics while visibly expressing sustainability.
Straw-Powered Production: The Self-Insulated Factory in Slovakia
Bjørn Kierulf (CEO Ecococon)
In Voderady, Slovakia, EcoCocon’s new production hall exemplifies sustainable industrial design. Constructed using the company’s own straw wall panels, the facility achieves exceptional thermal performance, eliminating the need for a conventional heating system. This energy-efficient building operates entirely on solar power, aligning with EcoCocon’s commitment to eco-friendly practices. The production hall boasts an annual capacity of 60,000 m² of timber-straw wall panels, significantly advancing the availability of bio-based construction materials.
EcoSpai in Tarragona

Gabriel Patricio Kosowski (EcoCocon España)
Municipal building for public facilities promoted by the Monte Roig del Camp City Council in Tarragona. Built with 256 EcoCocon panels anchored to a polished concrete foundation slab and roofed with exposed CLT panels. All vertical finishes on the thatched panels are finished with clay plaster, and all the building’s installations are visible. The goal is to create a healthy work environment, and the building itself is an educational element, as all its functions are visible.
