How do the material choices we champion at revalu translate into real-world architecture?
From adaptive reuse and circular construction to bioclimatic design and locally sourced materials, revalu’s 2026 Open Call highlights different ways of working with existing resources, rethinking what we build with, and making more environmentally responsible choices.
Here’s a first look at this year’s winners and finalists.

El Fil Verd Estudi d'Arquitectura
Garraf Natural Park, Barcelona, Spain · 2020
