📝 Description
This LoRA is trained on the iconic Grand Roof Ring from Expo 2025 Osaka, Japan — the world’s largest wooden ring-shaped roof structure, stretching approximately 2 kilometers in circumference.
It captures the bold circular form, intricate wooden lattice patterns, and the gentle harmony between traditional materials and futuristic scale.

The Grand Ring, designed by renowned architect Sou Fujimoto and constructed by Obayashi Corporation, encircles the entire Expo site. This LoRA is ideal for rendering visionary cityscapes, monumental pavilions, or symbolic architectural compositions.
