PDX Airport’s New 9 Acre Wood Roof….As if It Were Grown There
Jacob Dunn

Jacob Dunn, a visionary in sustainability-focused architecture, shares the transformative story behind the redesign of PDX Airport's new main terminal, featuring a 9-acre mass timber roof, forest-like shading, and an array of living trees.

This project is not just a renovation — it's a reimagining of how buildings interact with their natural surroundings and impact their local and regional ecosystems.

Through unprecedented transparency in sourcing from native and small-holder properties, every piece of wood used is traceable back to its origin, showcasing a profound level of accountability and connection to the land.

Jacob emphasizes that this level of detail and dedication to sustainability isn't reserved for monumental projects like airports. He’s inspiring and equipping architects and builders everywhere, regardless of project size, to adopt similar practices.

This initiative is about making sustainable, traceable sourcing the norm, not the exception, in how we build.

Explore how the PDX renovation project is crafting a future where architecture and nature exist in harmony.
