Executive Summary for the Great Green Exposition

The Great Green Exposition will transform thirty acres of London's historic Syon Park into a fully walkable temporary English hamlet for several weeks in late summer and early autumn 2027. Designed by renowned New Urbanist Lew Oliver, the exposition will feature over 110 pavilions hosting businesses, innovators, artisans, and nonprofits, all built using locally sourced modular structures that will be repurposed after the event. Guided by four interwoven environments (the built, natural, social, and temporal), the exposition will offer immersive exhibits ranging from carbon-negative building materials to hands-on workshops in sustainable construction. Anticipating one million visitors from around the globe, the event aims to prove that sustainability need not require sacrificing beauty, comfort, or prosperity, demonstrating regenerative building technologies and human-scale urbanism as tangible, walkable reality rather than abstract concepts.
