Alejandro Aravena's Elemental and Holcim Collaborate on Carbon-Neutral Housing at the 2025 Venice Biennale

From May 10 to November 23, 2025, a carbon-neutral housing prototype by Elemental, led by Alejandro Aravena, will feature at the Venice Architecture Biennale. This initiative combines the firm's social housing expertise with Holcim's low-carbon concrete technology to address climate and humanitarian crises. The design uses ECOPact concrete, which emits 30% less CO₂ and is recyclable. While the specific design details remain undisclosed, the model aims for scalability, reflecting Aravena's successful housing models like Quinta Monroy. This project represents Holcim's continued collaboration with leading architects to promote sustainable construction practices.

If we don't build billions of square meters, the humanitarian crisis escalates; but if we build, we worsen the environmental crisis. - Alejandro Aravena
