The former solid ground envelope becomes a slab, structural piers and opaque structural glazing.","The 10 m lower eave and 16 m main ridge retain the previous interpretation. The mapped front raised area defines the open canopy extent; missing level dimensions, framing spacing, glazed bay subdivision and roof seams are proportional interpretations from the photograph, not survey measurements.","Temporary event banners, equipment and photographic textures are omitted.
