Why Do We Deconstruct World’s Fairs?

Osaka, Japan

大阪市、日本

• Expo structures are testing large-scale material recovery.

• The Grand Ring has become a global case study, but isn’t necessarily living up to its potential

• Temporary architecture is reshaping conversations about permanence.

The Grand Ring at Expo 2025 has become one of the most discussed construction projects in Japan.

Beyond its scale and engineering, the project has sparked important conversations about what should happen after major events end.

Researchers, designers, and builders are closely watching how materials will be recovered, redistributed, and reused. The project offers a rare opportunity to evaluate whether circular construction principles can operate at an international scale.

I visited Osaka in May 2026 and was able to see the deconstruction from afar.
