The Great Green Exposition will be a once-in-a-generation public event showcasing the future of sustainable living, regenerative design, and human-scale urbanism. For several weeks in late summer to early autumn 2027, the grounds of historic Syon Park in London will be transformed into a full-scale, walkable temporary English hamlet — conceived by Lew Oliver Inc. and constructed using locally sourced, modular structures that will be repurposed after the event.
