波打つ金属屋根：無柱大スパンの展示場

Design a convention centre in the manner of Fumihiko Maki's Makuhari Messe — an immense exhibition hall roofed by a continuous shallow metal wave carried on external tubular steel masts and stays, so the interior is entirely free of columns and the structure is read from outside. Compose a very long undulating aluminium roof, slender external steel masts with tension rods, a fully glazed concourse running the length beneath, a reflecting pool and paved forecourt, flat coastal daylight, low wide view along the facade, 24mm lens, architectural photography, ultra photorealistic, 8K
