The success of LUMBER 4 lies in its pioneering approach, demonstrating that mass timber can rival traditional steel and concrete in both economic and environmental terms. Constructed in record time thanks to a high level of prefabrication and innovative building techniques, the project achieved an impressive 53% reduction in greenhouse gas emissions. This feat aligns with the European Union’s Taxonomy regulations, positioning LUMBER 4 as a model of sustainability and eco-conscious design.

What truly sets LUMBER 4 apart is its all-timber construction, which uses wood as the key material for its structure, insulation, and protection. The building’s distinctive green-painted, curved wooden façade has captured international attention, making it one of the most widely shared architectural projects on social media in 2023. This unique combination of aesthetic appeal and sustainability has propelled LUMBER 4 to global recognition.
