Build a grand casino with one large...

Build a grand casino with one large circular central hall and four very wide, long, straight hallways, each connected to the center by a wide, open passage. Continue one solid black-concrete floor seamlessly through the entire interior, from the center to the ends of all four hallways. Outside, add one connected gray platform that fills the spaces between and around the building, ending at a neat edge. Use deep-red walls, sandstone pillars, gold trim, a broad dome resting on the central hall, and roofs joined to the hallway walls. Keep colors solid and uniform, with no gradients, speckles, or scattered patches. Add statues, small trees, and paths on the outdoor platform. Make the casino grand, elegant, and richly detailed while keeping the layout clear.
